Polygons

Clear, exam-focused notes on polygon names, interior and exterior angles, diagonals and symmetry, with diagrams and fully worked examples.

A complete 19-page IGCSE guide to polygons. It covers what makes a shape a polygon, naming polygons, regular vs irregular, and convex vs concave. The main sections teach the interior angle sum, interior and exterior angles of regular polygons, and finding the number of sides from a given angle. It also covers diagonals and symmetry in regular polygons, and finishes with algebraic angle problems. Every formula comes with a clear diagram and step-by-step worked examples. It ends with a summary, a keyword guide and exam tips.
