Quote:
Let $ABC$ be a triangle and let $DEF$ be the contact points of the incircle with the sides of $ABC$. Let $P$ and $Q$ be on sides $AB$ and $AC$ respectively such that $PQ$ is parallel to $BC$, and so that $PQ$ is tangent to the incircle $\omega$. Let $M$ be the midpoint of $PQ$. Finally, let $T$ be the intersection of $EF$ with $BC$. Show that $MT$ is tangent to $\omega$.
