a triangle has side lengths of 12,16, and 20 centimeters. is it a right triangle?

First, we see if we can simplify. So we type GCF(12,16,20) and we get 4.

We divide the 3 side lengths by 4:
12/4 = 3
16/4 = 4
20/4 = 5

And lo and behold, we get a Pythagorean Triple of 3, 4, 5. So yes, this is a right triangle.
