Summer looked at the formula for the Pythagorean Theorem, a2 + b2 = c2, she said that it didn’t matter which sides of a right triangle were a, b, and c. Is she correct?

In the Pythagorean Theorem, a and b represent the two legs of the right triangle, and either leg can be assigned to either variable. The side c must represent the hypotenuse, which is opposite the right angle and is the longest side. Therefore, a and b are interchangeable, but c is not; choice D is correct.
