Isogonal conjugation with respect to triangle A1. A2A3 compares point X to point Y such that the YAi line is symmetrical to line XAi relative to the angle bisector Ai (i1, 2, 3). This transformation has many interesting properties. In particular, it translates into each other two wonderful points of the triangle - Brocard's points.
