Determine whether a Triangle with side lengths of 11, 60 and 61 is a Right Triangle

A Right Triangle must satisfy the Converse of the Pythagorean Theorem: a² + b² = c²
From the given side lengths, let a = 11, b = 60, c = 61  (c cannot be less than a or b)
a² + b² = (11)² + (60)²
a² + b² = 121 + 3,600 = 3,721
c² = (61)² = 3,721
a² + b² = c²  (3,721 = 3,721)
Therefore, a Triangle with side lengths of 11, 60 and 61 is a Right Triangle
Note: Since the side lengths are positive integers and the GCF(11, 60, 61) = 1, they are a primitive Pythagorean Triple
