There exists a triangulation point for which the triangles
,
, and
have equal Brocard angles. This point is a triangle center known as the equi-Brocard center and is Kimberling center
.
It has a complicated triangle center function given by the unique positive real root of a tenth-order polynomial in
, which is actually fifth-order in
. The polynomial can be found by computing the distances from each of the vertices to the triangulation point

and using the equation

where is the Brocard angle and
