# 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`
