Pythag's Theorem.

Use the sliders to choose the BASE and HEIGHT of your right-angled triangle. Next, tick the box to show the squares made by the sides of the triangle. Compare the areas (especially the 2 smaller ones vs. the larger one). Can you see a pattern? Play with the BASE and HEIGHT of your triangle and see if your pattern exists for ALL right-angled triangles.
