Circle Theorem 2

1. Move Points & Observe
  • Drag point A, B, or C and observe how the angles change.
  • Pay close attention to:
    • The angle between the tangent and the chord.
    • The angle subtended by the chord in the alternate segment.
2. Record Your Observations
  • What is the relationship between angle ABC and angle CAP?
  • How does moving points A, B, or C affect the relationship?
  • What role does the chord play in this relationship?
  • What role does the segment play in this relationship?
3. Prepare to Discuss At the end of the activity, you’ll share your findings with the class. Be ready to explain what you observed and how it relates to the theorem. Utilize the parts of the circle to explain your findings.
