This math puzzle asks students to cut out five shapes numbered 1-5 and rearrange them around a hypotenuse so that they fit together based on Pythagoras' theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. Students are then asked to create a formula that proves the puzzle and reflect on what the puzzle is teaching them about Pythagoras' theorem.
