X-parabola and related centers: X(12064)-X(12079)

This preamble and centers X(12064)-X(12079) were contributed by César Eliud Lozada, February 27, 2017.

Let A*B*C* be the side triangle of the medial and orthic triangles of ABC, and let A'B'C' be the medial triangle of A*B*C*. Then A, B, C, A', B', C' lie on a parabola here named the X-parabola of ABC. Some properties of this parabola are:

It has barycentric equation: (b^2-c^2)^2*y*z+(c^2-a^2)^2*z*x+(a^2-b^2)^2*x*y=0
It passes through the vertices of the antipedal triangle of X(477) and centers X(476), X(523), X(685), X(850), X(892), X(2395), X(2501), X(4024), X(4036), X(4581), X(4608), X(5466), X(8599), X(10412) and X(12079).
Its directrix and the Euler line of ABC are parallel, therefore its axis and the Euler line of ABC are perpendicular.
Its 4th intersection with the circumcircles of ABC and A'B'C' is X(476)
The focus and vertex are X(12064) and X(12065), respectively.
Its axis is the line {523, 5972}, trilinear polar of X(12066).
Its directrix is the line {30, 10279}, trilinear polar of X(12067).
The perspector is X(115) and the center is X(523).
The dual conic of the X-parabola has center X(620), perspector X(4590) and passes through the vertices of the cevian triangle of X(4590) and centers X(2), X(32), X(439), X(593), X(1509), X(2482), X(3926), X(4027), X(7058), X(7794), X(11128), X(11129).

Let t_a, t_b, t_c be the tangents to the X-parabola at A, B, C, respectively; the triangle A_tB_tC_t bounded by these tangents is here named the X-parabola-tangential triangle of ABC. Barycentric coordinates of A-vertex are:
A_t = -(b^2-c^2)^2 : (a^2-c^2)^2 : (a^2-b^2)^2

The appearance of (T,i) in the following list means that triangles T and X-parabola-tangential are perspective with perspector X(i): (ABC, 115), (extouch, 12069), (2nd Hatzipolakis, 12070), (incentral, 12071), (intouch, 12072), (Lemoine, 12073), (Macbeath, 12075), (medial, 523), (orthic, 512), (Steiner, 12076), (symmedial, 12077), (Yff contact, 12078).

The X-parabola is the isogonal conjugate of line X(110)X(351) (the tangent to circumcircle at X(110)), and the isotomic conjugate of line X(99)X(110) (the tangent to Steiner circumellipse at X(99)). (Randy Hutson, March 9, 2017)

The X-parabola-tangential triangle is the anticevian triangle of X(115). (Randy Hutson, June 27, 2018)

For a construction, see Paris Pamfilos, A Gallery of Conics by Five Elements, Forum Geometricorum 14 (2014) 295-348, paragraph 13.3, page 346: construct a conic tangent to the line at infinity, i.e. a parabola, tangent to three lines a, b, c and passing through [D], i.e. with given axis-direction.

Let ABC be a triangle with incenter X(1)=I and let a' be perpendicular line to AI through I. Denote as A'_b the intersection of a' and the perpendicular line to AB through B and denote as A'_c the intersection of a' and the perpendicular line through C to AC. Perpendicular lines to a' through A'_b and A'_c cut BC at A_b and A_c, respectively. Points B_c, B_a, C_a, C_b are built cyclically. Then these six points lie on a conic here named the Ashrafov-Montesdeoca conic. (See: Angel Montesdeoca, HGT-Feb 17, 2017).

As a point P moves on the circumcircle, the centroid of the 12 excenters of triangles ABC, BCP, CAP, ABP traces a curvilinear triangle, T. Let A', B', C' be the vertices of T, and (Oa), (Ob), (Oc) the circles whose arcs form the sides of T; the triangle A'B'C' is also the orthic triangle of the anticomplementary triangle of OaObOc, and OaObOc the medial triangle of the excentral triangle of A'B'C'. Then A'B'C' is homothetic to the medial triangle at X(12512). Let A" be the intersection, other than A', of circles (Ob) and (Oc), and define B" and C" cyclically. Then A"B"C" is the excentral triangle of A'B'C', and the anticomplementary triangle of OaObOc. Also, A"B"C" is homothetic to the extraversion triangle of X(10) (i.e. the complement of the excentral triangle) at X(12512). (Randy Hutson, July 21, 2017)

CENTERS ASSOCIATED WITH THE ELLIPSE IE59: X(12835)-X(12841)

This preamble and centers X(12835)-X(12841) were contributed by Peter Moses, March 29, 2017.

Let IE59 denote the inellipse with perspector X(59). The center of IE59 is X(13006), and IE59 passes through X(i) for these i:

55, 56, 181, 202, 203, 215, 1124, 1335, 1362, 1397, 1672, 1673, 1682, 2007, 2008, 3235, 3236, 3237, 3238, 6056, 7005, 7006, 7066, 10799, 12835, 12836, 12837, 12838, 12839, 12840, 12841

This ellipse IE59 is the locus of the centers of similtude (insimilicenter and exsimilicenter) of the incircle with Tucker circles. Also, IE59 intersects the incircle in X(1362) and three other points, so that the corresponding four Tucker circles are tangent to the incircle. The Tucker circle through X(1362) has the following parameter:

arccos[(t² - s²)/(t² + s²)], where t = r + 4R.

The centers of the other three Tucker circles are the extraversions of X(970), and they lie on the Brocard axis. Not only are these circle internally tangent to the incircle, but they are also externally tangent to the two corresponding excircles. In this section, the names for centers X(12835) to X(12841), the notation "Tucker (X,p)-circle" represents the Tucker circle with center X and parameter p.

Let f(a,b,c,x,y,z) = b⁴c⁴(a - b - c)²(b - c)⁴x² - 2a⁴b²c²(a - b)² (a - b + c)(c - a)²(a + b - c)yz. The ellipse IE59 is given by the barycentric equation f(a,b,c,x,y,z) + f(b,c,a,y,z,x) + f(c,a,b,z,x,y) = 0.

Possibly the earliest mention of IE59 occurs in TCCT, page 238, in a list of inscribed ellipses; in that list, this ellipse is denoted by W(X₁₁).

Let P be a point on the circumcircle and D a point on the line BC. Let U and V be the reflections of D in PB and PC, respectively. The envelope of lines UV when D moves on BC is a parabola. Let P be its focus and d_a its directrix. The envelope of d_a as P moves on circumcircle is a circle, O_a. Define (O_b) and (O_c) cyclically. The radical center of the circles (O_a), (O_b), (O_c) is X(13419); see Euclid #611. (Angel Montesdeoca, February 6, 2020)

Let P be the trilinear pole of the tangent to the MacBeath circumconic at a point Q. (i.e., P = X(3)-cross conjugate of a point Q on the MacBeath circumconic.) The locus of the polar conjugate of P as Q varies is an inconic centered at X(13567), and passing through X(338), X(1146), and X(3269). The Brianchon point (perspector) of this inconic is X(2052).

Inscribe three squares into a triangle ABC such that each square has two vertices on two distinct sides of ABC and the other vertices of the three squares coincide at the vertices of another triangle A'B'C'.

Let the squares be σ_a=B'C'A_cA_b, σ_b=C'A'B_aB_c and σ_c=A'B'C_bC_a with B_a, C_a on BC, C_b, A_b on CA, A_c, B_c on AB and centers A_o, B_o, C_o, respectively. This construction has four solutions. For each case, the triangle A'B'C' will be named here the tri-squares triangle of ABC and the triangle A_oB_oC_o will be referred here as tri-squares-central triangle of ABC.

Barycentric coordinates of the first points on each square are shown in the following table:

A_c = 2*SB+SC+3*S : 2*SA+SC : 0

A_o = 3*(SB+SC)+4*S : 2*SA+SC+S : 2*SA+SB+S

Centers related to the 2nd tri-squares triangles: X(13757)-X(13850)

This preamble and centers X(13757)-X(13850) were contributed by César Eliud Lozada, July 10, 2017.

Tri-squares triangles were defined in the preamble of X(13637). In this section, A'B'C' is the 2nd tri-squares-triangle and A_oB_oC_o is de the 2nd tri-squares-central triangle.

A'B'C' and the circumsymmedial triangle are directly similar with center X(13779).

The appearance of (T, n) in the following list means that triangles A'B'C and T are inversely similar with center X(n):

Theorem: If any conic C be inscribed in a given triangle and a confocal to it pass through the circumcenter, then the Aiyar-circle-of-C through the intersections of these two confocals touches the nine-points circle of the triangle. Reference: Ramaswami Aiyar: A General Theorem on the Nine-points Circle, Proceedings of the Edinburgh Mathematical Society, Volume 15, February 1896, pp. 74-75.

Notes: The touchpoint of the nine-points circle and the Aiyar-circle-of-the-Steiner inellipse is X(1313). For the Brocard inellipse and the McBeath inconic, the confocal conics through X(3) are degenerated.

Let DEF be the orthic triangle. Let Ab be the point in which the line through B perpendicular to AB meets the perpendicular bisector of segment BD . Let Ac be the point in which the line through C perpendicular to AC meets the perpendicular bisector of segment CD. Define Bc, Ba, Ca, Cb cyclically.
