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:c2 = a2 + b2 − 2ab cos(C)It helps us solve some triangles. Let's see how to use it....
Law of cosines also known as cosine rule or cosine law, helps to find the length of the unknown sides of a triangle when other two sides and angle between them is given. Learn formulas at BYJU’S.

One method for solving for a missing length or angle of a triangle is by using the law of sines. The law of sines, unlike the law of cosines, uses proportions to solve for missing lengths. The ratio of the sine of an angle to the side opposite it is equal for all three angles of...
