Thus, the law of cosines is valid when C is an obtuse angle. Case 2. Now consider the case when the angle at C is right. The cosine of a right angle is 0, so the law of cosines, c2 = a2 + b2 – 2 ab cos C, simplifies to becomes the Pythagorean identity, c2 = a2 + b2 , for right triangles which we know is valid. Case 3.
