- Let ABC be a triangle, P a point, A'B'C' the cevian triangle of P,
O' the center of the cevian circle of P, and A"B"C" the circumcevian
triangle of P.
The cirvumcircle of AA"O' intersects the cevian circle of P
at A1, A2. Similarly B1,B2 and C1, C2.
The Lines A1A2, B1B2, C1C2 concur at a point on PO'.
