Weba2 + b2 – 2 ab cos C. 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. WebSwitching from Law of Cosines to Law of Sines may introduce the ambiguous case and create extraneous solutions, so it is better to stick with Law of Cosines as much as possible. If you do change to Law of Sines, you can test your results by substituting ALL of your sides and angles into the proportion.
