A triangle has sides with lengths of 60 centimeters, 63 centimeters, and 87 centimeters. Is it a right triangle
lozanna [386]
We can check this by seeing if Pythagorean's theorem applies. The longest side is the hypotenuse, so let's see if this is true:
60^2+63^2 = 87^2
7569 = 7569

This is, indeed correct, thus, this <em>is </em><em>a right triangle.</em>
