pedal circle passes through the anti steiner point?












1














Given a triangle $triangle ABC$ and $P$ is an arbitrary point. Let $triangle DEF$ be the cevian triangle of $P$ with respect to (wrt) $triangle ABC$ and $triangle XYZ$ be the pedal triangle of $P$ wrt $triangle ABC$. Is it true that the circumcircle of $triangle XYZ$ intersects the circumcirle of $triangle DEF$ at the Poncelet point of $A, B, C, P$ and the Anti Steiner point of $P$ wrt $triangle DEF$? If so, how can we prove it?
