Question

A triangle has sides with lengths of 12 inches 80 inches in 85 inches is it a right triangle?

Answer 1

no

Explanation:

If it is a right triangle, the side lengths will work in the Pythagorean theorem equation: a² + b² = c²

12² + 80² = 144 + 6400 = 6544

85² = 7225

The lengths do not work.

Answer: no
