Law of Cosines WORKSHEET DESCRIPTION
This worksheet provides some purposeful practice for finding the missing angles and lengths of triangles using the cosine rule. Section A has three questions where a missing side is required when given the other two sides and the included angle. Section B requires learners to calculate an angle given all three sides. Section C has a mixed set of questions, and section D requires missing values from compound shapes.
