Question

Sherry thinks 7, 7 and 12 are side lengths of a right triangle. Do you agree or disagree? Justify your reasoning. PLEASE NOW!!!! PLEASE!!!!!!

Answer 1

disagree

Explanation:

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

longest side = 12 ⇒ 12² = 144

7² + 7² = 49 + 49 = 98

Since 144 ≠ 98 then triangle is not right
