    We are given a triangle with sides corresponding to a, b and c. If this is a right triangle, then b being the longest side, the triangle's sides follow the Pythagorean theorem that states c2 = a2 + b2. In this case, the problem states a2 + b2 < c2. we can assume values and use cosine law. theta then is greater than 90 degrees which is an obtuse angle. In this case, cos theta is negative. The conditions that apply are A, C and D
