Determine whether a Triangle with side lengths of 1.5, 2 and 2.5 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 = 1.5, b = 2, c = 2.5  (c cannot be less than a or b)
a² + b² = (1.5)² + (2)²
a² + b² = 2.25 + 4 = 6.25
c² = (2.5)² = 6.25
a² + b² = c²  (6.25 = 6.25)
Therefore, a Triangle with side lengths of 1.5, 2 and 2.5 is a Right Triangle
