Pythagoras Theorem Proof


1. Create any right angled triangle by adjusting the blue points. Importantly the side length a must be less than b 2. Show the squares that are formed by each of the triangles. Note the area of each square. 3. Show the Perigal Dissection Objects 3.a.) Convince yourself that the blue pieces have the same area as the blue square by shifting and rotating the Perigal Objects. 3.b.) Show Pythagoras Theorem result by dragging the orange and blue pieces to cover the area of the purple square. That is the area of the blue square + area of the orange square = area of the purple square.
