Using the Pythagorean Theorem

You've just been shown how the Pythagorean theorem works. Formal proofs show that the theorem is true not just for this triangle but for all right triangles. Once you know the equation a²+ b² = c² is true, then you can use it to solve all kinds of problems. Try the Pythagorean theorem with:

baseball: throwing the runner out
ladders: breaking and entering

pyramids: scaling the pyramids
