v1 mapping, pending teacher review. Only AQA and Edexcel are mapped so far. The first 3 pilot worksheets and their worked answers are available; remaining worksheets are coming soon. All videos are still coming soon.

Retrieval: Inscribed angles and quadrilateral sums
Fluency: Identify relevant points on a circle
Reasoning: Name the relevant theorem and justify its applicability.
Application: Justify a multi-step cyclic angle calculation
Common misconception: A circle theorem requires the correct points and tangency conditions.

Video brief

Model how to use same-segment and cyclic quadrilateral theorems. Explain each step; pause for a matching shadow question.
