Theorem (Law of Cosines). c^2 = a^2 + b^2 - 2ab Cos [C]. Proof. Place triangle ABC on a Cartesian coordinate system such that angle C is at the origin and length a lies on the x-axis. Then length b is on the other ray from the origin. We can easily identify the coordinates of two of the vertices: Vertex C lies at (0,0), and vertex B lies at (a,0).Notice that like the Law of Sines, the Law of Cosines is really three laws. ...

The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. It is most useful for solving for missing information in a triangle. For example, if all three sides of the triangle are known, the cosine rule allows one to find any of the angle measures. Similarly, if two sides and the angle between them is known, the cosine rule allows …Browse law of sines and cosines resources on Teachers Pay Teachers, a marketplace trusted by millions of teachers for original educational resources. ...
