GETTING IT ... TOGETHER

Photocopy this set of six polygons, preferably onto card. Cut them all

out carefully.

(It's probably best to work in pairs for this one.)

(A) Fit the five quadrilaterals together to make a square whose side

is the same length as the longest side of the triangle.

(B) Now fit the four identical pieces together to make a square whose side is the same length as one of the other sides of the triangle.

(C) So what? Does this demonstrate anything you knew already?
