Question

Does the given side lengths make a right triangle? 9, 37, 40

Answer 1

Basically can you do pythagoras on it
40 would have to be the hypotenuse as it’s the largest, so if 9^2 + 37^2 = 40^2 then we have a right triangle
9^2 + 37^2 = 1450
40^2 = 1600
1450 doesn’t equal 1600, so those side lengths don’t make a right triangle
