Question

A triangle has sides with lengths of 9 feet, 12 feet , and 14 feet. Is it a right triangle

Answer 1

9^2 + 12^2 = 14^2

81 + 144 = 196

225 ≠ 196

Since 225 is not equal to 196, the Pythagorean theorem is not satisfied, and this triangle is not a right triangle.

Explanation:

using the Pythagorean theorem i.e. h^2=p^2+b^2
