This example demonstrates how to copy a given angle using GeoGebra. Key mathematical concepts include the properties of angles and geometric construction. Using commands such as Segment, Angle, Line, Circle, and Intersect, the angle can be accurately copied. Suitable for middle school and above students learning geometric construction.

GeoGebra Commands & Parameters

  1. Segment(A, B) → a
  2. Segment(A, C) → b
  3. Angle(C, A, B) → α
  4. Line(D, E) → c
  5. Circle(A, B) → d
  6. Circle(D, Segment[A, B]) → e
  7. Intersect(d, b, 1) → F
  8. Intersect(e, c, 2) → G
  9. Circle(G, Segment[F, B]) → f
  10. Intersect(e, f, 1) → H
  11. Angle(G, D, H) → target
