How to prove it.

Abstract
In this episode of “How To Prove It”, we prove a
simple yet surprising collinearity associated with any
triangle. We do so in two different ways and then
contrast the two proofs. It would be instructive for a
student to study these proofs and also the remarks
made at the end.
