Young Pythagoras can't seem to stay out of trouble. Every time he tries to help, people get angry. On a trip to Egypt, his curiosity helps him to discover the secret of the right triangle. This story is a clever introduction to the Pythagorean Theorem.

A fictionalized look at Pythagoras as he discovers his famous theorem. He is depicted as a curious boy who travels with his father from Samos to Alexandria, where he meets a builder named Neferheperhersekeper, who introduces him to the right angle. He begins to experiment, observing and noting the fixed and unvarying mathematical nature of triangles--right triangles, to be precise.
