This example demonstrates how to construct congruent angles using geometric methods. Key math concepts involved include angles, circles, intersection, and angle measurement. The construction utilizes GeoGebra commands such as Ray, Circle, Intersect, and Angle to form congruent angles. Suitable for middle school students and above for learning geometric construction techniques and for mathematical teaching demonstrations.

GeoGebra Commands & Parameters

  1. Ray(A, B) → f
  2. Ray(A, C) → g
  3. Ray(D, E) → h
  4. Circle(A, C) → c
  5. Circle(D, Segment[A, C]) → d
  6. Intersect(c, f, 1) → F
  7. Intersect(d, h, 1) → G
  8. Circle(G, Segment[C, F]) → e
  9. Intersect(d, e) → H, I, ,
  10. Ray(D, H) → i
  11. Angle(f, i) → α
  12. Angle(i, f) → β
  13. Angle(f, i) → γ
  14. Angle(f, g) → δ
  15. Angle(i, h) → ε
