Pythagorean Theorem

The Pythagorean Theorem states that the square of the hypothenuse is equal to the sum of the square of the other two legs in a right triangle. The formula for the Pythagorean Theorem is  a^2+ b^2= c^2  
The pythagorean Theorem has been used for hundreds of years to solve geometric problems. Here is a simple example. A 12 foot ladder is placed 4 feet from the wall. How far up the wall will the ladder reach? Let's see how you can apply the pythagorean theorem to solve this problem. The following video solves this problem.
