Question

Which of the following sets could be the sides of a right triangle?

a. {2, 3, sq root 13)
b. {2, 2, 4}
c. (1, 2, sq root 3}

Answer 1

Your answer is a. {2, 3, √13}. This is because you can use the formula a² + b² = c², which can only be used with right triangles, and it is correct. 2² + 3² = 13, and so the hypotenuse would be √13.
I hope this helps!
