Chapter 15: Theorem of Pythagoras
The theorem of Pythagoras is a very important mathematical proof that relates the lengths of the sides of a
right-angled triangle. Over the years, mathematicians have discovered many different ways to prove the theorem
A Pythagoras tree is made up of squares. Each group of squares (three touching squares that are a similar
colour) enclose a right-angled triangle. Pythagoras trees were invented by a Dutch mathematician, Albert E.
Bosman, and they are named after the ancient Greek mathematician, Pythagoras.
