Each worksheet is carefully crafted to increase the complexity of the questions ...The Law of Cosines For any triangle: a, b and c are sides. C is the angle opposite side c The Law of Cosines (also called the Cosine Rule) says: c 2 = a 2 + b 2 − 2ab cos (C) It helps us solve some triangles. Let's see how to use it. Example: How long is side "c" ... ? We know angle C = 37º, and sides a = 8 and b = 11 The Law of Cosines is used to find the remaining parts of an oblique (non-right) triangle when either the lengths of two sides and the measure of the included angle is known (SAS) or the lengths of the three sides (SSS) are known. In either of these cases, it is impossible to use the Law of Sines because we cannot set up a solvable proportion.
