The Law of Cosines is useful for finding: the third side of a triangle when we know two sides and the angle between them (like the example above) the angles of a triangle when we know all three sides (as in the following example)

Cosine Rule a2 = b2 + c2 - 2bc cos ∠x b2 = a2 + c2 - 2ac cos ∠y c2 = a2 + b2 - 2ab cos ∠z

Law of Cosines. In any triangle, given two sides and the included angle, the third side is given by. the Law of Cosines formula: c2 = a2 + b2 – 2ab cos(C) Try this Drag any vertex of the triangle. Note that the length of the unknown side c is continually recalculated using the Law of Cosines.

Depending on the information we have available, we can use the law of sines or the law of cosines. The law of sines relates the length of one side to the sine of its angle and the law of cosines relates the length of two sides of the triangle to their intermediate angle.
