This example demonstrates the relationship between the base angles of an isosceles trapezoid. Key mathematical concepts include the properties of trapezoids and angles. Using GeoGebra commands such as Segment, Angle, Line, Rotate, Ray, and Intersect, students can explore the relationship between the base angles of an isosceles trapezoid. Suitable for middle school and above students for geometric construction.

GeoGebra Commands & Parameters

  1. Segment(A, D) → a
  2. Segment(A, B) → b
  3. Angle(D, A, B) → α
  4. Line(B, a) → e
  5. Rotate(A, (-α), D) → A'
  6. Angle(A', D, A) → β
  7. Ray(D, A') → c
  8. Intersect(e, c) → C
  9. Segment(B, C) → d
  10. Segment(D, C) → f
  11. Angle(A, B, C) → γ
  12. Angle(D, C, B) → δ
