This example demonstrates how to construct the rotation of a point given an angle and a center. Key mathematical concepts include angles and rotation transformations. It uses GeoGebra commands such as Ray, Circle, and Intersect. Suitable for middle school and above students learning geometric transformations.

GeoGebra Commands & Parameters

  1. Ray(C, D) → f
  2. Ray(C, E) → g
  3. Circle(B, A) → c
  4. Ray(B, A) → h
  5. Circle(C, Segment[B, A]) → d
  6. Intersect(d, g, 1) → F
  7. Intersect(d, f, 1) → G
  8. Circle(A, Segment[F, G]) → e
  9. Intersect(c, e) → H, I, ,
  10. Circle(F, Segment[A, H]) → k
