The Law of Cosines is also used to determine the measure of an unknown angle when the lengths of all the sides of the triangle are known. This is referred to as SSS. Students should be reminded of the fact that the longest side of a right triangle, the hypotenuse, is located opposite the right angle which is the largest angle of the triangle.

SAS. Our given information is two sides and the included angle. We could use Law of Sines or Cosines to find the missing angles, but it is better to use the Law of Cosines since the arccosine function will distinguish between acute and obtuse angles. C = 180 – A – B. SSS. We know the three sides of the triangles. C = 180 – A – B . Example:
