Atriangle has sides with lengths of 11 feet, 16 feet, and 20 feet. is it a right triangle?

It is not a right triangle because it would not work out when tested using Pythagorean’s Theorem. (Hyp^2=Opp^2 + Adj^2)

11^2+16^2=20^2

377<400

This would make it an Obtuse Triangle

Helpful Hint:

The sum of the smallest sides squared > Longest Side Squared - Acute Triangle

The sum of the smallest sides squared = Longest Side Squared - Right Triangle

The sum of the smallest sides squared < Longest Side squared - Obtuse Triangle
