Simple formula: Pythagorean Theorem

Explanation:

#a^2 + b^2 = c^2#

This is the Pythagorean Theorem. It only works when using a right triangle, and can be used to find a missing side if you have the other side lengths. The neat thing is you only need TWO of the three variables. If you had A and C, you could say

#c^2 - b^2 = a^2#

Hope it helps :)
