Recall the Pythagorean theorem:
c^2 = a^2 + b^2
where c is the hypotenuse (which is also the longest side of a right triangle) and a & b are the legs.
Substitute each side lengths to the equation. Of course the longest side is c, and the remaining sides are a and b. If the set of side lengths satisfies the pythagorean equation, therefore, it is a right triangle.
Hope this helps~ :3
Use Pythagorean Theorem to determine which set of sides can be the sides of a right triangle.
