Problems Involving the Cosine Rule

              Problems Involving the Cosine Rule

              Students learn how to use the Cosine Rule to work out an unknown length or angle in a non-right-angled triangle.

              Later, as learning progresses they solve problems involving bearings and triangles with algebraic lengths.
