本范例演示旋转的基本概念，包括正角和负角的旋转。核心数学概念涉及角度和旋转。通过使用GeoGebra命令如Rotate、Segment、Circle等，可以直观地展示旋转效果。适合初中及以上学生学习几何变换。

GeoGebra 命令及参数

  1. Distance(A, B) → d
  2. Rotate(B, α, A) → C
  3. Segment(A, B) → f
  4. Segment(A, C) → g
  5. Circle(A, (0.2 * f)) → c
  6. Intersect(c, f) → C_1,
  7. Intersect(c, g) → D,
  8. CircleSector(A, C_1, D) → h
  9. CircleSector(A, B, C) → k
  10. CircleSector(A, D, C_1) → p
  11. CircleSector(A, C, B) → q
  12. Circle(A, B) → r
