#### Pythagorean Theorem Investigation: It's As Easy Asâ€¦ a, b, c

Oftentimes, the Pythagorean Theorem is taught from the standpoint of, "Here is the formula, let's practice finding the lengths of the sides of triangles!" without helping students understand or develop the relationships between the sides on their own. This activity helps students experience those relationships using multiple approaches, prove why the theorem is true, and practice using it.
