A Concurrency from the Reflection of the Incircle's Contact Points across the Incenter


	Let ABC be a triangle. Let A', B', and C' be the intersections of the incircle with BC, CA, and AB, respectively. Let A'', B'', and C'' be the reflections of A', B', and C' across the incenter. Then AA'', BB'', and CC'' are concurrent.
