Determine whether a Triangle with side lengths of 10, 20 and 24 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 = 10, b = 20, c = 24  (c cannot be less than a or b)
a2 + b2 = (10)2 + (20)2
a2 + b2 = 100 + 400 = 500
c2 = (24)2 = 576
a2 + b2 ≠ c2  (500 ≠ 576)
Therefore, a Triangle with side lengths of 10, 20 and 24 is NOT a Right Triangle
Note: Since a2 + b2 < c2  (500 < 576), the Triangle is an Obtuse Triangle
