This example demonstrates how to construct congruent angles through rotation. Key mathematical concepts include angle properties and geometric construction. It uses GeoGebra commands such as Point, Rotate, Angle, Segment, and Ray. Suitable for middle school and above students to learn about angle properties and geometric construction.

GeoGebra Commands & Parameters

  1. Point(xAxis) → A
  2. Rotate(B, α, A) → B'
  3. Angle(B, A, B') → β
  4. Segment(A, B) → f
  5. Ray(A, B') → g
  6. Ray(A, B') → h
  7. Ray(A, B) → i
