Ceva Product |
|
Given ∆ABC and points P and Q. Let PaPbPc be the anticevian triangle of P. Let A1 is the intersection point of lines BC and PaQ, and cyclically. Then triangles ABC and A1B1C1 are perspective and the perspector is the Ceva Product of points P and Q. 
PaPbPc = anticevian triangle of point P. A1 = BC ∩ PaQ. B1 = CA ∩ PbQ. C1 = AB ∩ PcQ. R = Ceva Product of P and Q = Perspector of triangles ABC and A1B1C1.
