Question

A triangle has sides with lengths of 72 inches, 78 inches, and 30 inches. Is it a right triangle?

Answer 1

yes

Using the converse of Pythagoras' identity.

If the square of the longest side is equal to the sum of the squares on the other 2 sides then the triangle is right.

72² + 30² = 5184 + 900 = 6084

Then the triangle is right
