Question

A triangle has sides with lengths of 86 centimeters, 90 centimeters, and 36 centimeters. Is it a right triangle?

Answer 1

Explanation:

IF it is a right traingle , then the Pythagorean theorem would apply

c^2 = a^2 + b^2 where c is the longest side

does 90^2 = 86^2 + 36^2 ???

8100 = 7396 + 1296 ???

8100 = 8692 ??? NO....it is NOT a right triangle
