The Intersections of Extended Cevians with Three Circumcircles of Subtriangles
Let P be a point in the interior of the triangle ABC. Draw the three circumscribed circles for the triangles APB, APC, and BPC. Let X, Y, and Z be the intersections (other than P) of the extensions of AP, BP, and CP with the circles opposite A, B, and C. Then:
AP
AX
BP
BY
CP
