Equi-Brocard Center
There exists a triangulation point Y for which the triangles BYC, CYA, and AYB have equal Brocard angles. This point is a triangle center known as the equi-Brocard center and is Kimberling center X_(368).
It has a complicated triangle center function given by the unique positive real root of a tenth-order polynomial f(a,b,c) in alpha, which is actually fifth-order in alpha^2. The polynomial can be found by computing the distances from each of the vertices to the triangulation point
and using the equation
where omega is the Brocard angle and Delta is the triangle area to obtain the three equations
where Delta_(xyz) is the area of the triangle with side lengths x, y, and z (which can be computed using Heron's formula).
