The give side measures are 24, 30, 36.

Since the measure of the longest side is 36, So let c = 36, a = 24 and b = 30.

Then apply Pythagorean theorem: .

           (Substitute  c = 36, a = 24 and b = 30)

Evaluate powers: .

Since , the triangle is not right triangle.

The measures , the triangle is not right triangle.
