Question

Hillary needs to know if the triangle shown is a right triangle. Which equation should she use to help?

Answer 1

a2+b2=c2

Explanation:

A right triangle is a triangle in which one of the angles is a 90∘ angle. A triangle can be determined to be a right triangle if the side lengths are known. If the lengths satisfy the Pythagorean Theorem (a2+b2=c2) then it is a right triangle.
