Focus on circle theorems and transformations gcse. Start with “Apply Alternate Segment Theorem”, then explain the idea in your own words.
Year 10 / GCSE learners practise circle theorems and transformations gcse.
The activities include Apply Alternate Segment Theorem, Apply Chords and Radii, Apply Circle Theorems to Solve Problems, and related practice. The checked support below includes video, teaching, worksheet, practice. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
