About this circle theorems game
This free circle theorems game gives GCSE-level students practice applying the key circle theorem rules — the angle at the centre, the angle in a semicircle, angles in the same segment, and opposite angles in a cyclic quadrilateral — to find missing angles on labelled diagrams. Choose which theorems to include, set your question count and time limit, then work through as many as you can. It's a solid way to build recognition of which rule applies to which diagram ahead of exams.
