Given a list of triangles, return a corresponding list of booleans (True or False) specifying whether they are right triangles. Each item in the list of triangles is a list of three side lengths for the triangle. For example, given a list of three triangles [[3,4,5], [12,5,13], [1,1,2]], the output would be [True, True, False]. Assume the side lengths are allowable for a triangle.
