WebThe law of cosines (also called “cosine law”) tells you how to find one side of a triangle if you know the other two sides and the angle between them. The law of sines (i.e. the “sine law”) does not let you do that. Instead it tells you that the sines of the angles are proportional to the lengths of the sides opposite those angles.
