Sample Response: First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squar
ed and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse. What did you include in your response? Check all that apply.
If a2 + b2 = c2, the triangle is right.
If c2 < a2 + b2, the triangle is acute.
If c2 > a2 + b2, the triangle is obtuse.
