Chapter 465 - Pythagorean Theorem

One of the most basic and useful formulas that can be used whenever you have a right triangle.

a^2 + b^2 = c^2

For any of you who might've never heard of this formula before, this is a formula that can be used to find the third length of any given right triangle.

All you need to know, is that C is always the longest edge of the triangle.
