Determine whether a Triangle with side lengths of 1.25, 3 and 3.25 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 = 1.25, b = 3, c = 3.25  (c cannot be less than a or b)
a² + b² = (1.25)² + (3)²
a² + b² = 1.5625 + 9 = 10.5625
c² = (3.25)² = 10.5625
a² + b² = c²  (10.5625 = 10.5625)
Therefore, a Triangle with side lengths of 1.25, 3 and 3.25 is a Right Triangle
