Determine whether a Triangle with side lengths of 11, 59 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 = 59, c = 61  (c cannot be less than a or b)
a² + b² = (11)² + (59)²
a² + b² = 121 + 3,481 = 3,602
c² = (61)² = 3,721
a² + b² ≠ c²  (3,602 ≠ 3,721)
Therefore, a Triangle with side lengths of 11, 59 and 61 is NOT a Right Triangle
Note: Since a² + b² < c²  (3,602 < 3,721), the Triangle is an Obtuse Triangle
