The Pythagorean theorem. You might not know what this is, what it does, nor what it is used for. Well let me tell you I had the same problem when my math teacher first told me about it. Now that I know, I can share all of the stuff with you. First of all the Pythagorean theorem is a math equation. This math equation is used to find the length of a missing side in a triangle.

The equation is a to the second power times b to the second power equals c to the second power. You may not know what the second power means, but all that means is that you multiply the number times the number twice.
