KS4 – MYP 4–5 Mathematics | Booklet 7.3: Circle Theorems

My original Grade 10 Mathematics Standard MYP teaching booklet on circle theorems, supplied as a downloadable PDF.

Explore angles at the centre and circumference, cyclic quadrilaterals, tangents, chords and the alternate-segment theorem through notes, diagrams, worked examples and practice questions.

This is the original 33-page booklet, with its original questions, equations, diagrams and numbering preserved. A free YouTube lesson link and the following recording note have been added.

Recording note: This lesson uses an earlier Circle Theorems booklet. Page and question numbers differ; match exercises by their diagrams and given values. The current booklet contains additional material not covered in this recording.

Original wording clarification: in the alternate-segment red boxes on pages 11–12, the tangent–chord angle equals the corresponding angle in the alternate segment; it is not half that angle. Page 17 states the correct equality. The original pages remain unchanged.
