Question

A triangle has sides with lengths of 15 inches, 20 inches, and 25 inches. Is it a right triangle?

Answer 1

37 inches

Hope this helps!

Answer 2

Yes.

Explanation:

If the side lengths verify in the Pythagorean theorem, then it is a right triangle.

a² + b² = c²

15² + 20² = 25²

225 + 400 = 625

625 = 625

Since these values come out true when using the Pythagorean Theorem, this triangle is a right trinagle.
