Forming expressions for area and perimeter and simplifying to show equivalence. There is a great deal of scope for differentiation here, with two activities which take the idea further (The last one is not my own, but from a resource called 'Materials to Support able mathematicians in KS3') More…Includes application of trigonometry ratios in finding the general rule for areas of regular polygons.
