When you are given three measurements of a triangle, How can you tell if it is a right triangle or not?

If you have three side length of a triangle, say, a, b, and c (a <= b <= c), then the triangle is right if and only if

c^{2} = a^{2} + b^{2}. If c^{2} < a^{2} + b^{2}, then the triangle is acute and, finally, the triangle is obtuse if c^{2} > a^{2} + b^{2 }

I appreciate the help!

You are welcome.
