Question

Which set of numbers could represent the lengths of the sides of a right triangle? a.7, 24, 25 b.8, 9, 10 c.9, 11, 14 d.15, 18, 21

Answer 1

The answer is a. 7, 24, 25, because 7^2 + 24^2 does equal 25^2, which is Pythagoras' Theorem which can only work on right triangles. I hope this helps!
