First of all, if the sides are integers, they have to be all different for us to even consider that a triangle may be a right one. If at least two are the same (if they are integers, remember!), then the triangle isn't right.
Then, let's order the sides: a < b < c. Then the triangle with these sides is a right one if the Pythagorean theorem holds: a^2 + b^2 = c^2.
