Question

Which of the triangles are right triangles? Please be 100% sure about your answers. I will mark Brainliest!

Answer 1

1 is wrong because the measurements do not work for the pythagorean theorem.
3 is wrong because using the pythagorean theorem with those measurements would not work.
4 is wrong because the only way that 4 would work is if the hypotenuse was 3√2 not 3√3

The correct answer is 2 because that is the only one that actually works with the pythagoran theorem. 

√41^2 = 41
5^2 + 4^2 = 25 + 16 = 41
41 = 41
