2 resourcesProving the Sine Rule, Cosine Rule and Area Formula: Ordering
Put the steps of each proof in order: area = ½ab sin C, the sine rule and the cosine rule, each with its diagram. Any order where every step follows from the ones before it is accepted. Prints as a worksheet with answers.
🧮 ToolVisual Proofs
Animated visual proofs of Pythagoras’ theorem, of the sums of integers, odd numbers, squares and cubes, and of key results in algebra, geometric series, trigonometry and inequalities. They play like Shape Formulas: drag the bar…
These are the pages for Proving the formulae in the GCSE + AQA Level 2 Further Maths scheme of work, following Pearson Edexcel GCSE (9–1) Higher (1MA1), plus AQA Level 2 Further Mathematics (8365). Open this topic in Mr Wells Maths to see it alongside the rest of the course.
