This example demonstrates how to construct and verify the properties of vertical angles using GeoGebra. Key math concepts include angles, intersecting lines, and symmetry. Construction involves commands like Point, Semicircle, Intersect, Segment, Angle, Mirror. Suitable for middle school and above students learning basic geometry concepts.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Point(xAxis) → B
  3. Semicircle(A, B) → c_1
  4. Semicircle(B, A) → d_1
  5. Intersect(xAxis, yAxis) → C
  6. Segment(C, B) → a_1
  7. Point(c_1) → D
  8. Segment(C, D) → b_1
  9. Angle(B, C, D) → a
  10. Mirror(D, C) → E
  11. Segment(A, C) → e
  12. Segment(C, E) → f
  13. Angle(A, C, E) → b
  14. Angle(D, C, A) → c
  15. Angle(E, C, B) → d
