Circle Theorems: GCSE / IGCSE

These GCSE / IGCSE circle theorems lessons build from discovery of key results through to tangent reasoning, chord problems and multi-theorem solutions. Topics include:

  • Introducing circle theorems: discovering results such as the angle at the centre and angles in the same segment
  • Tangents circle theorems: the angle between a radius and tangent, and the alternate segment theorem
  • Applying circle theorems involving tangents, including more challenging diagrams
  • Applying multiple circle theorems together to solve a complex problem
  • Intersecting chords: introduction and reasoning, including similarity arguments where used
  • Problem solving with circle theorems and dedicated exam-style practice
