Trigonometry: Sine, Cosine and Area Rules [Foundation]

The purpose of this course is to teach learners the skills they need to be able solve for unknown sides and angles in all triangles. We begin by recapping the tools learnt in Grades 9 and 10 and then progress on to the Area Rule, Sine Rule and Cos Rule to help solve for these unknowns. We finish the course by applying these tools in mixed questions involving triangles, where learners need to think about which tool would be best to use.
