Collineation mappings involving Gemini triangle 100: X(30030)-X(30099)

Extending the preambles just before X(24537), X(26153), and X(27378), let m(X) denote the (A,B,C,X(2); A',B',C',X(2)) collineation image of X = x : y : z, where A'B'C' = Gemini triangle 100, as in centers X(30030)-X(30099). Then

m(X) = (a b^2 + a c^2 + b^2 c + b c^2) x - b (b c + a b - a c) y - c (b c - a b + a c) z : :

and m(X) is on the Euler line if and only if X is on the Euler line. (Clark Kimberling, December 12, 2018)

Frégier points: X(30181)-X(30257)

This preamble and centers X(30181)-X(30257) were contributed by César Eliud Lozada, December 15, 2018.

Let Γ be a conic and P a fixed point on it. The sides of any right angle with vertex P cut Γ again in P' and P". Then all the lines P'P" intersect in a common point Q_Γ(P).
(See: Frégier's Theorem in MathWorld)

This section deals with some named conics in the plane of a triangle ABC. The point Q_Γ(P) is denoted here as the P-Frégier point of Γ.

It can be proved that if Γ is a rectangular hyperbola then Q_Γ(P) lies in the line at infinity. Isogonal conjugates of these points in the infinity are also included in this section.

The appearance of (i, j) in the following table means that Q_Γ(X(i)) = X(j) for the indicated conic Γ:

Endo-homothetic centers: X(30274)-X(30434)

This preamble and centers X(30274)-X(30434) were contributed by César Eliud Lozada, December 19, 2018.

This section consists of the endo-homothetic centers of the family of triangles homothetic with the orthic triangle of a reference triangle ABC. This family is composed by the following 37 triangles:

anti-Ascella, anti-Atik, 1st anti-circumperp, anti-Conway, 2nd anti-Conway, 3rd anti-Euler, 4th anti-Euler, anti-excenters-reflections, 2nd anti-extouch, anti-Honsberger, anti-Hutson intouch, anti-incircle-circles, anti-inverse-in-incircle, 6th anti-mixtilinear, 1st anti-Sharygin, anti-tangential-midarc, anti-Ursa minor, anti-Wasat, circumorthic, Ehrmann-side, Ehrmann-vertex, 2nd Ehrmann, 2nd Euler, 1st excosine, extangents, intangents, 1st Kenmotu diagonals, 2nd Kenmotu diagonals, Kosnita, Lucas antipodal tangential, Lucas(-1) antipodal tangential, orthic, submedial, tangential, inner tri-equilateral, outer tri-equilateral, Trinh.

For definitions and coordinates of these triangles, see the index of triangles referenced in ETC.

A table showing the endo-homothetic centers among these triangles can be seen here.

In the plane of a triangle ABC, let
P = the point on segment BC such that AP bisects angle BAC, and define Q and R cyclically;
Pb = the point on AC suchb that PPc besects angle APC, and define Qb and Ra cyclically;
Pc = the point on AB such that PPc besects angle APB, and define Qc and Rb cyclically;
S = RRb∩QQc, and define T and U cyclically;
X = RRa∩QQa, and define Y and Z cyclically;
Then the lines SX, TY, UZ concur in X(30420). (It is known that the six points Rc, Qa, Pb, Rb, Ac Pc lies on an ellipse; its center is X(46329). See X(30420). (Steven Verpoort, February 17, 2024)

Centers associated with intriangles and extriangles: X(30514)-X(30516)

Contributed by Clark Kimberling and Peter Moses, January 1, 2019.

Following TCCT (page 196), the intriangle of a point P = p: q : r (barycentrics) is the central triangle having A-vertex

A' = 0 : b (c q + b r cos A) : c (b r + c q) cos A

and the extriangle of P is the central triangle having A-vertex

A'' = -a p (c q + b r cos A)(b r + c q cos A) : a q (c q + b r cos A)(a r + c p cos B) : a p (a r + c q cos A)(a q + b p cos C)

Properties of A'B'C' and A'''B'''C'':

1. A'B'C' is inscribed in ABC, which is inscribed in A''B''C''.

2. The locus of P for which A'B'C' is perspective to ABC is the Darboux cubic, K004; the locus of the perspector is the Thomson cubic, K002.

3. The locus of P for which A''B''C'' is perspective to ABC is the union of the circumcircle, the lines BC, CA, AB, the line at infinity, and the cubic K004. If P is on the line at infinity, then the perspector is on the cubic K162.

4. The locus of P for which A''B''C'' is perspective to the cevian triangle of P is the same as for property 3.

5. The locus of P for which A'B'C' is perspective to the anticevian triangle of P is the union of the lines BC, CA, AB, and the cubic K004.

6. A'B'C'and A''B''C'' are perspective with perspector X(6).

7. The intriangle of X(2) is perspective to the circumsymmedial triangle at X(3).

8. The intriangle of X(6) is perspective to the 1st Ehrmann triangle (see X(8537) at X(12027); to the Artzt triangle (see X(9742) at X(6776), and to the anti-Honsberger triangle at X(184).

Centers associated with duple triangles: X(30543)-X(30550)

Suppose that A'B'C' is a central triangle in the plane of a reference triangle ABC, and that barycentrics for A' are u : v : w. The duple of A'B'C' is here introduced as the central triangle A''B''C'' having A'' = u : w : v; for example, the duple of the excentral triangle has A'' = -a : c : b. It is easy to prove that if two triangles are perspective, then their duples are perspective. (Clark Kimberling, January 1, 2019)

In the plane of a triangle ABC, suppose that A'B'C' is a triangle and L is a line. Let A'' be the reflection A' in L, and define B'' and C'' cyclically. The triangle A''B''C'' is here named the L-reflection of A'B'C'. If A'B'C' is a central triangle and L a central line, then A''B''C'' is a central triangle. (Clark Kimberling), January 11, 2019)

Let T denote the Euler-line-reflection of ABC. Peter Moses (January 12, 2019) found that T is perspective to the following triangles, with perspectors as indicated:

ABC: X(523)
Schroeter (anticevian triangle of X(523); see X(8286), X(10276)): X(523)
tangential: X(30715)
Macbeath: X(30716)
orthic-of-medial (anti-6th-mixtilinear; see X(11363)): X(30717)
5th Euler (see X(3758): X(30718)
circum-medial: X(23)
Gemini 44: X(23)
Gossard: X(30)
reflection of ABC in X(3): X(30)
infinite altitude: X(74)
circum-orthic: X(186)
Carnot (Johnson, the reflection of ABC in X(5)): X(30)
Kosnita: X(186)

The triangle T is also perspective to these triangles: Euler, Trinh, 2nd Euler, 5th Euler, Artzt, anti-Artzt, tangential of tangential, anti-1st-Euler, anti-Hutson intouch, anti-incircle-circles (see X(11363), orthic-of-medial, Ehrmann side-triangle.

The locus of a point P such that the cevian triangle of P is perspective to T is the cubic pK(14618,264). The locus of P such that the anticevian triangle of P is perspective to T is the cubic pK(112,648). (Peter Moses, January 13, 2019)

and m(X) is a self-inverse mapping such that m(X) is collinear with X(2) and X; e.g., m(Euler line) = Euler line and m(Nagel line) = Nagel line. Also, m(nine-point circle) = nine-point circle. The fixed points of m are X(2) and every point on the line X(325)X(523), which is the isotomic conjugate of the circumcircle. Among the fixed points are X(i) for these i: 2, 325, 523, 684, 850 ,3260, 3265, 3266, 3267, 20735, 30736, 30737. (Clark Kimberling, January 19, 2019)

Conics associated to pairs of orthologic or parallelogic triangles: X(31353)-X(31375)

This preamble and centers X(31353)-X(31375) were contributed by César Eliud Lozada, January 27, 2019.

I) Conics associated to a pair of orthologic triangles:

Let T'=A'B'C' and T"=A"B"C" be two orthologic triangles. Denote a'_b and a'_c the perpendicular lines from A' to A"C" and A"B", respectively, and build b'_c, b'_a, c'_a,c'_b cyclically. Then these six lines are tangent to a conic Φ'_t, here named the orthologic tangential-conic T' to T".
Swap T' and T", repeat the above construction and name the respective lines a"_b, a"_c, b"_c, b"_a, c"_a, c"_b. Then these six lines are tangent to another conic Φ"_t, here named the orthologic tangential-conic T" to T'.
Let A'_b=a'_b ∩ B'C' and A'_c=a'_c ∩ B'C' and define B'_c, B'_a, C'_a, C'_b cyclically. Then these six points lie on a conic Φ'_p, here named the orthologic conic T' to T".
Swap T' and T", repeat the above construction and name the respective points A"_b, A"_c, B"_c, B"_a, C"_a, C"_b. Then these six points lie on another conic Φ"_p, here named the orthologic conic T" to T'.

II) Conics associated to a pair of parallelogic triangles:

Let T'=A'B'C' and T"=A"B"C" be two parallelogic triangles. Denote a'_b and a'_c the parallel lines from A' to A"C" and A"B", respectively, and build b'_c, b'_a, c'_a,c'_b cyclically. Then these six lines are tangent to a conic Ψ'_t, here named the parallelogic tangential-conic T' to T".
Swap T' and T", repeat the above construction and name the respective lines a"_b, a"_c, b"_c, b"_a, c"_a, c"_b. Then these six lines are tangent to another conic Ψ"_t, here named the parallelogic tangential-conic T" to T'.
Let A'_b=a'_b ∩ B'C' and A'_c=a'_c ∩ B'C' and define B'_c, B'_a, C'_a, C'_b cyclically. Then these six points lie on a conic Ψ'_p, here named the parallelogic conic T' to T".
Swap T' and T", repeat the above construction and name the respective points A"_b, A"_c, B"_c, B"_a, C"_a, C"_b. Then these six points lie on another conic Ψ"_p, here named the parallelogic conic T" to T'.

If T' and T" are orthologic (parallelogic) triangles and P is the orthologic (parallelogic) center T' to T", then the orthologic (parallelogic) conic T' to T" does not depend on T". Moreover, the orthologic conic T' to T" and the parallelogic conic T' to T" coincide. Therefore, when T' are P are given, a more convenient name for this conic Φ'_p= Ψ'_p is P-orthoparallelogic conic of T'. A similar coincidence occurs for the tangential conics Φ'_t= Ψ'_t and therefore a better name for this conic is P-orthoparallelogic tangential-conic of T'.

If P = x:y:z (barycentrics) then the center of the P-orthoparallelogic conic of ABC is:

O′_p = x^2*(y+z)*((y+z)*(x^4-(y-z)^2*y*z)-x*(y^2+z^2)*(-x^2+y^2+z^2)-(y^3+z^3)*x^2) : :

and its perspector is:

Q′_p = x*(y+z)*F(x,y,z)*F(x,z,y) : :, where F(x,y,z) = (x^2*(2*x*y+x*z+2*z^2)-(y-z)*(2*y*((x+z)*y+z^2)+x*z*(y+z)))

The center of the P-orthoparallelogic tangential-conic of ABC is O'_t=complement-of-P and its perspector is:

Q′_t = (x*(2*z+y)+y*(y+z))*(x*(2*y+z)+z*(y+z)) : :

The appearance of (i, j) in the following list means that X(j)=center of the X(i)-orthoparallelogic conic of ABC:
(1,3588), (2,2), (3,31353), (4,17807), (5,31354), (6,31355), (7,7955), (30,3163), (511,11672), (512,1084), (513,1015), (514,1086), (515,23986), (516,23972), (517,23980), (518,6184), (519,4370), (522,1146), (523,115), (524,2482), (525,15526), (526,18334), (536,13466), (542,23967), (690,23992), (726,20532), (826,15449), (1503,23976), (3566,15525), (3906,17416) , (7927,15527), (17430,17429)

The appearance of (i, j) in the following list means that X(j)=perspector of the X(i)-orthoparallelogic conic of ABC:
(1,31356), (2,2), (3,31357), (4,17808), (6,31358)

The appearance of (i, j) in the following list means that X(j)=perspector of the X(i)-orthoparallelogic tangential-conic of ABC:
(1,31359), (2,2), (3,13599), (4,15740), (5,22268), (6,31360), (8,7320), (20,31361), (69,17040), (75,17038), (95,17041), (99,9293), (264,17039), (550,3521), (668,9267), (3244,5559), (3629,13622)

Note: For P in the infinity, O′_p lies in the Steiner inellipse, Q′_p = P and Q′_t = P.

Centroids of curvatures: X(31393)-X(31502)

This preamble and centers X(31393)-X(31502) were contributed by César Eliud Lozada, February 08, 2019.

Let (O₁), (O₂), (O₃) be three circles with distinct and non-collinear centers. Denote I₁, I₂, I₃ the internal centers of similitude of {(O₂), (O₃)}, {(O₃), (O₁)} and {(O₁), (O₂)} , respectively. Then the lines O₁I₁, O₂I₂, O₃I₃ concur.

Assume that exact trilinear coordinates of the centers are O_i = ( U_i, V_i, W_i ) and their radius are R_i (i = 1..3). If M is the trilinear matrix of the centers then the given point of intersection Q is:

Q = M^T.| ρ₁ ρ₂ ρ₃ |^T, where ρ_i = 1/R_i, i.e., ρ_i is the curvature of the circle (O_i).

In fewer words:

Q = ∑ ρ_iU_i : ∑ ρ_iV_i : ∑ ρ_iW_i, i=1..3

Then, for obvious reasons, the point Q is here named here the centroid of curvatures of the circles (O₁), (O₂), (O₃).

Suppose a fourth circle (O₄) is added to the above configuration and let Q_ℓ be the centroid of curvatures of (O_i), (O_j), (O_k). Then the lines O_iQ_i concur at:

Q = ∑ ρ_iU_i : ∑ ρ_iV_i : ∑ ρ_iW_i, i=1..4

The last extension provides a geometrical recursive construction of the centroid of curvatures of any number n ≥ 3 of circles with distinct and not collinear centers.

The appearance of (C, n) in the following list means that X(n) is the centroid of curvatures of the three circles C:

Triangles associated to Soddy circles: X(31528)-X(31605)

This preamble and centers X(31528)-X(31605) were contributed by César Eliud Lozada, February 19, 2019.

Let A'B'C' be the intouch triangle of ABC and (S_a), (S_b), (S_c) their Soddy circles. Let A_oB_oC_o be the outer-Soddy triangle of ABC (touchpoints of Soddy circles and the circle internally tangent to them) and and A_iB_iC_i the inner-Soddy triangle of ABC (touchpoints of Soddy circles and the circle externally tangent to them). Then quadrilaterals B'C'C_oB_o and B'C'B_iC_i are cyclic. (See Antreas Hatzipolakis, Hyacinthos #28871)

The circles (O_a) and (I_a) circumscribing B'C'C_oB_o and B'C'C_iB_i, respectively, will be named here the 2nd A-outer-Soddy circle and 2nd A-inner-Soddy circle, respectively and triangles O_aO_bO_c and I_aI_bI_c are called here the 2nd outer-Soddy triangle and 2nd inner-Soddy triangle, respectively. Barycentric coordinates of A-vertices are:

O_a = (-a+b+c)*a-2*S : b*(-a+b+c) : c*(-a+b+c)

I_a = (-a+b+c)*a+2*S : b*(-a+b+c) : c*(-a+b+c)

Peter Moses found that vertices B_o, C_o, B_i, C_i are concyclic, and similarly the other quartets of vertices (see Hyacinthos #28873). Denote Q_a the center of B_oC_oB_iC_i and cyclically Q_b and Q_c. The triangle Q_aQ_bQ_c will be named here the Soddy triangle of ABC and has first vertex Q_a = -1/(-a+b+c) : 1/(a-b+c) : 1/(a+b-c).

The appearance of (T, n) in the following list means that triangles T and Q_aQ_bQ_c are perspective with perspector X(n):

The appearance of (T, i, j) in the following list means that triangles T and Q_aQ_bQ_c are orthologic with orthologic centers X(i) and X(j): (inner-Soddy, 176, 1), (outer-Soddy, 175, 1)

Points associated with cubics pK(U',U'): X(31610)-X(31643)

This preamble and centers X(31610)-X(31643) were contributed by Clark Kimberling and Peter Moses, February 20, 2019.

Suppose that U = u : v : w (barycentrics) is a point in the plane of a triangle ABC. The self-inverse Gemini triangle based on U is defined as the triangle with vertices

A' = - u : v + w : v + w, B' = - v : w + u : w + u, C' = - w : u + v : u + v .

The triangle A'B'C' is perspective to the cevian triangle of a point X = x : y : z if and only if X lies on the cubic

v w (y - z) (y z - x y - x z) + w u (z - x )(z x - y z - y x) + u v (x - y)(x y - z x - z y) = 0,

this being, Bernard Gibert's notation ( Parallel Tripolars Cubics) the cubic pK(U',U'), where U' = isotomic conjugate of the crosspoint of X(2) and U; that is, U' = 1/(v+w) : 1/(w+u) : 1/(u+v). Points on this cubic, which we denote by Γ(U), include the following:

1 : 1 : 1 = X(2) = centroid
v w : w u : u v = isotomic conjugate of U
1/(v + w ) : 1/(w + u) : 1/(u + v) = isotomic conjugate of the complement of U
u/(v + w ) : v/(w + u) : w/(u + v)
v w/(v + w ) : w u/(w + u) : u v/(u + v)
(-u + v + w)/(v + w ) : (u - v + w)/w + u) : (u + v - w)/(u + v)
u - d : v - d : w - d, where d = sqrt(v w + w u + u v)
u + d : v + d : w + d, where d = sqrt(v w + w u + u v)

Let t1 = u^2(v+w) + v^2(w+u) + w^2(u+v) + uvw, t2 = (-u+v+w)(u-v+w)(u+v-w), and t = sqrt(t1/t2). Then two more points on the cubic are

u/(-u + v + w) - t : v(u - v + w) - t : w(u + v - w) - t
u/(-u + v + w) + t : v(u - v + w) + t : w(u + v + w) - t

If U is a triangle center, then A'B'C' is a central triangle and those ten points on Γ(U) are triangle centers. Note that the points involving square roots are nonreal for some choices of U and a,b,c.

Let DEF be the cevian triangle of v w : w u : u v, so that D = 0 : 1/v : 1/w, E = 1/u : 0 : 1/w, F = 1/u : 1/v : 0. The perspector of A'B'C' and DEF is the point

u(-u^2 + v^2 + w^2) : v(u^2 - v^2 + w^2) : w(u^2 + v^2 - w^2) = U*-Ceva conjugate of U, where U* = isotomic conjugate of U.

The appearance of

i	j(1), j(2), ..., j(n)	k	Kxxx

in the following table means that points on Γ(X(i)) include X(j(1)), X(j(2)), ..., x(j(n)), that X(k) is the perspector of A'B'C' and DEF, and that Γ(X(i)) = Kxxx .

Points associated with cubics pK(U*Y,U): X(31644)-X(31648)

This preamble and centers X(31644)-X(31648) were contributed by Clark Kimberling and Peter Moses, February 20, 2019.

Suppose that U = u : v : w (barycentrics) is a point in the plane of a triangle ABC. The self-inverse Gemini triangle based on U is defined (above, in the preamble just before X(31610) as the triangle with vertices

A' = - u : v + w : v + w, B' = - v : w + u : w + u, C' = - w : u + v : u + v .

The triangle A'B'C' is perspective to the anticevian triangle of a point X = x : y : z if and only if X lies on the cubic

(y - z) (y z u^2 + x^2 v w) + (z - x) (z x v^2 + y^2 w u) + (x - y) (x y w^2 + z^2 u v) = 0,

this being, in Bernard Gibert's notation (see Special Isocubics in the Triangle Plane (Section 1.3)) the cubic pK(U*Y, U), where

Y = 1/(v + w) : 1/(w + u) : 1/(u + v) = cevapoint of X(2) and U, and * = barycentric product.

Points on this cubic, which we denote by Γ*(U), include the following:

1 : 1 : 1 = X(2) = centroid
u : v : w = U
1/(v + w ) : 1/(w + u) : 1/(u + v) = cevapoint of X(2) and U = isotomic conjugate of the complement of U
u/(v + w ) : v/(w + u) : w/(u + v)

The appearance of

i	j(1), j(2), ..., j(n)	k	Kxxx

in the following table means that points on Γ*(X(i)) include X(j(1)), X(j(2)), ..., x(j(n)) and that Γ*(X(i)) = Kxxx .

3rd and 4th isodynamic-Dao triangles and related centers: X(31683)-X(31720)

This preamble and centers X(31683)-X(31720) were contributed by César Eliud Lozada, March 15, 2019.

Let A_oB_oC_o be the orthic triangle of ABC. Denote by A', B', C' the 1st isodynamic points X(15) of AB_oC_o, BC_oA_o and CA_oB_o, respectively, and A", B", C" the 2nd isodynamic points X(16) of AB_oC_o, BC_oA_o and CA_oB_o , respectively. Then the triangles A'B'C' and A"B"C" are equilateral. (Dao Thanh Oai, pers. comm., March 12, 2019).

The triangles A'B'C' and A"B"C" are here named here 3rd isodynamic-Dao and 4th isodynamic-Dao triangles, respectively. (See also triangles A*B*C* and A**B**C** constructed in Hyacinthos 28021 [Aug 11, 2018, Tran Quang Hung and Randy Hutson]). These triangles have the following properties and relations:

Orthopolar circles: X(31727)-X(31840)

This preamble and centers X(31727)-X(31840) were contributed by César Eliud Lozada, March 22, 2019.

Let T'=A'B'C' and T"=A"B"C" be two triangles. Then the orthopoles of the sidelines of T' with respect to T" and the orthopoles of the sidelines of T" with respect to T' lie on an ellipse having for center the midpoint of the orthocenters of T' and T". When T' and T" are inscribed in concentric circles, the ellipse is a circle. Also, under certain conditions, the orthopoles may be coincident or collinear. [R. Goormaghtigh: On pairs of triangles.

The ellipse just described is here named the orthopolar ellipse or orthopolar circle of T' and T".

This section deals with pairs of triangles inscribed in concentric circles. The appearance of (T', T", i) in the following lists means that X(i) is the center of the orthopolar circle of triangles T' and T".

Points I-Caph: X(31994)-X(32000)

This preamble and centers X(31994)-X(32000) were contributed by Clark Kimberling and Peter Moses, April 15, 2019.

Suppose that P = p:q:r (barycentrics). The Point I-Caph of P is the point given by

2qr + (p+q+r)p : 2rp + (p+q+r)q : 2pq + (p+q+r)r.

See sections below for Points II-Caph, III-Caph, and IV-Caph. The points in a Caph family of a point P all lie on the line PP*, where P* is the isotomic conjugate of P. (The name Caph is that of a a star, also known as Beta Cassiopeiae.)

The appearance of {i,j} in the following list means that X(j) = Point I-Caph of X(i):
