This video shows you how to find the area of a triangle when there isn't an obvious height and base length connected using a right angle. It builds on the work done previously on Sine Rule and Cosine Rule but showing how you can find the area of a triangle if you know the size of two sized connected by an included angle. Lots of worked examples are done and fully explained in an easy to understand way.
