Answer 1

Hey @Bookreader15. Would you like me to show you what and how to use the Pythagorean Theorem in an easy to understand way?

Answer 2

Whenever we have a right triangle (a right triangle is any that has a 90 Degree angle), like the one you have there - there is this rule, this law, that this guy Pythagoras came up with.

It's as simple as if you know two sides of the right triangle, you can calculate the third by the following equation.

a^2 + b^2 = c^2
