Question

Which of the following measurements could be the side lengths of a right triangle? A. 66 in, 88 in, 110 in

Answer 1

So the way to figure out the sides of a right triangle, is basically

A^2 + B^2 = C^2

Letter A is the only one that would work, because the first number squared (times itself), added to the second number squared, would equal the third number squared. This is a basic principle of the pythagorean theorem, which I can explain in more detail if you'd like. :)
