Let $ABC$ be a triangle with $AB<AC$, let $G,H$ be its centroid and otrhocenter. Let $D$ be the otrhogonal projection of $A$ on the line $BC$, and let $M$ be the midpoint of the side $BC$. The circumcircle of $ABC$ crosses the ray $HM$ emanating from $M$ at $P$ and the ray $DG$ emanating from $D$ at $Q$, outside the segment $DG$. Show that the lines $DP$ and $MQ$ meet on the circumcircle of $ABC$.
