This example demonstrates adjacent angles, which are two angles that share a common side and vertex. The core mathematical concepts involved include the properties of angles. Using GeoGebra commands such as Circle, Point, CircleArc, Segment, and Angle, the construction of adjacent angles is illustrated. Suitable for middle school and above students to learn geometric construction.

GeoGebra Commands & Parameters

  1. Circle(A, B) → c
  2. Point(c) → C
  3. CircleArc(A, B, C) → d
  4. Segment(C, A) → a
  5. Segment(B, A) → b
  6. Point(d) → D
  7. Segment(D, A) → e
  8. Angle(B, A, D) → α
  9. Angle(D, A, C) → β
  10. Angle(B, A, C) → γ
