This is the next video in the Pythagoras and Trig section of the Year 9 course looking at how we can use Trigonometry to find the missing side lengths of right angled triangles. Building on the last video I spend time looking at how we can use SOHCAHTOA to find the missing side length when given one angle and one side in a right angled triangle. There are a number of worked examples which frame the theory. I take time to explain the content in a clear and easy to understand way.
