Determine whether a Triangle with side lengths of 16, 63 and 65 is a Right Triangle

Given Side Lengths: 65, 63, 16
A Right Triangle must satisfy the Converse of the Pythagorean Theorem: a² + b² = c²
From the given side lengths, let a = 16, b = 63, c = 65  (c cannot be less than a or b)
a² + b² = (16)² + (63)²
a² + b² = 256 + 3,969 = 4,225
c² = (65)² = 4,225
a² + b² = c²  (4,225 = 4,225)
Therefore, a Triangle with side lengths of 16, 63 and 65 is a Right Triangle
Note: Since the side lengths are positive integers and the GCF(16, 63, 65) = 1, they are a primitive Pythagorean Triple
