# Thales' midpoint theorem

Think everything is half

The magician chopped his assistant through her midpoint (in half).

Thales used further ideas to determine his midpoint theorem that said.

If the midpoints of a triangle's sides are marked off i.e.

D is halfway between A and C

E is halfway between B and C

Then AB must be parallel to DE

And

DE is 1/2 length of AB

Yes HALF

DE=1/2AB
