If
a^2 + b^2 = c^2
Then the triangle is right
If
a^2+b^2 > c^2
Then the triangle is obtuse
If
a^2 + b^2 < c^2
Then the triangle is acute

Follow what eyust707 wrote. If the triangle is a right triangle, then if you use those three side lengths in the Pythagoras Theorem formula, it'll make it true.
This is how you test it:
