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
- Perpendicular radii and equal tangents
- Fluency
- Include perpendicular bisectors of chords
- Reasoning
- Name the relevant theorem and justify its applicability.
- Application
- Find angles and lengths in tangent diagrams
- Common misconception
- A circle theorem requires the correct points and tangency conditions.
