Determine whether a Triangle with side lengths of 11, 12 and 14 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 = 12, c = 14  (c cannot be less than a or b)
a² + b² = (11)² + (12)²
a² + b² = 121 + 144 = 265
c² = (14)² = 196
a² + b² ≠ c²  (265 ≠ 196)
Therefore, a Triangle with side lengths of 11, 12 and 14 is NOT a Right Triangle
Note: Since a² + b² > c²  (265 > 196), the Triangle is an Acute Triangle
