# Varignon's Theorem, Proof Without Words

### Solution

Let $BG=GD.$

### Acknowledgment

The proof is by Alik Palatnik (Shaanan Academic Religious Teachers' College, Haifa, Israel), The College Mathematics Journal, Volume 48, Number 5, November 2017, p 354.

Alik Palatnik thanks an anonymous reviewer for pointing out that the proof of the perimeter result generalizes to arbitrary quadrilaterals, whereas the proof of the area result does not.
