Let $A$ be one of the two distinct points of intersection of two unequal coplanar circles $C1$ and $C2$ with centers $O1$ and $O2$, respectively. One of the common tangents to the circles touches $C1$ at $P1$ and $C2$ at $P2$, while the other touches $C1$ at $Q1$ and $C2$ at $Q2$. Let $M1$ be the midpoint of $P1$.
