Mathematics

An explanation of how we can prove the Pythagorean theorem by using similar triangles. We draw an altitude inside the right triangle to create two new triangles that are similar to the original. We then write proportions to prove the Pythagorean theorem. We also do a regular ladder problem that involves the Pythagorean theorem.
