The Pythagorean Theorem has been used for thousands of years across the globe. The Pythagorean Theorem applies to right triangles. It states that the sum of the legs squared equals the hypotenuse squared. The legs are the vertical and horizontal sides of a right triangle. The hypotenuse is the longest side. It is also the diagonal side. The Pythagorean Theorem can be used to find the distance between any two points on a coordinate grid as well as to solve many real life math problems. For example, it can be used to solve for the height of the building in the problem above.
