CircleAngle
This example demonstrates the intersection of two chords in a circle. Key mathematical concepts include circle, angle, and geometric mean. It is constructed using GeoGebra commands such as Intersect and CircleArc. Suitable for middle school and above students to learn geometric construction.

GeoGebra Commands & Parameters

  1. Intersect(c, g) → B, C
  2. Intersect(c, f, 2) → E
  3. Intersect(c, f, 1) → G
  4. Intersect(f, g) → A
  5. CircleArc((0, 0), E, C) → k
  6. CircleArc((0, 0), G, B) → h
  7. Angle(G, A, B) → β
  8. Angle(E, A, C) → α
