Trigonometry 5 - The Cosine Rule (+ worksheet)
This is an excellent lesson looking at where the cosine rule comes from, when to use it and how to use it. This lesson has been adapted over the years and is very structured and organised. I often teach this lesson over two lessons as there is a lot of material here. 19 slides + worksheet.

The lesson includes:

+ a starter
+ lesson objectives
+ an explanation of where the rule comes from
+ very clear teaching slides (how and when to use the rule)
+ highlighted common mistakes made when using the rule
+ Exam-style questions (which also consolidates the sine rule)
+ answers with workings
+ Plenary.
