Just imagine, its a beautiful sunny day outside. You are standing outside, and wanting to trim some of the branches from the top of a tree in your yard. How do you know what size ladder to use to get up there?

Imagine building a house, you want all the rooms to be square, and the house to not be leaning to any side. How do you make sure of this?

Ever wonder how they make a baseball diamond?

How do they triangulate the exact location of your cell phone when you dial 911? How do they create the figures in your favorite video game? All of these questions can be answered either completely or partially with the use of the Pythagorean Theorem.

So what is the Pythagorean Theorem you ask? The Pythagorean Theorem states a relationship between the three sides of any right triangle. The relationship it presents is "In any right triangle, the sum of the squares of the length of the legs is equal to the square of the length of the hypotenuse." This theorem is credited to being discovered by a Greek Mathematician named Pythagoras, even though it was probably known before Pythagoras discovered it. Today there are around 100 proofs showing the Theorem is true. There is even 1 proof created by one of the United States former presidents. This Theorem is one of the most widely known Theorems in Mathematics.
