Circle TheoremsWorksheet

Practice questions in the order the notes teach them.

A complete 17-page IGCSE guide to circle theorems. It starts with the key vocabulary, then covers all eight theorems one at a time: angle at the centre, same segment, semicircle, cyclic quadrilaterals, the three tangent theorems, chord bisection and the alternate segment theorem. Each theorem comes with a clear diagram and a worked example. Later sections teach chain reasoning across two or three theorems, with a keyword guide for spotting which theorem to use. It ends with a quick-reference table, an exam checklist and exam tips.
