a squared plus b squared equals c squared
A math rule that says if you have a right triangle and you're too lazy to measure the longest side, just square the other two sides and add them like a math freak in a hurry.
My math teacher said I failed because I didn't use the Pythagorean Theorem. I said I didn't care because I'm rich and I have a calculator.
I tried to use this rule in my head during a test. It didn't work. I got a D.
My friend used this rule to cheat on a math quiz. He got an A and now he's my hero.
