Pythagoras Wheel

Pythagoras' theorem describes the relationship between the sides of right angle triangles.

How it Works

Rotate a wheel to allow fluid to flow between squares made from the sides of a right angle triangle.

Things to Try or Ask Around the Exhibit

  • What is the relationship between these squares?
  • Is this true for every right angle triangle?


Pythagoras was the first person to prove this theorem over 2500 years ago. He proved it using a geometric proof similar to the method demonstrated here.
