圆形分数可视化：基于 GeoGebra 的几何构造演示

GeoGebra 命令及参数

1. Circle(A, Size) → c
2. Point(c) → B
3. Segment(A, B) → a
4. Append(Sequence[Rotate[B, i, A], i, (360 / Parts_1)°, 359.9°, (360 / Parts_1)°], Rotate[B, 359.99°, A]) → ListP
5. CircleSector(A, B, Element[ListP, Shaded_1]) → Shade
6. Circle(C, Size) → d
7. Point(d) → D
8. Append(Sequence[Rotate[D, s, C], s, (360 / Parts)°, 359.9°, (360 / Parts)°], Rotate[D, 359.99°, C]) → ListP2
9. CircleSector(C, D, Element[ListP2, Shaded]) → Shade2
10. Segment(C, D) → b
11. Zip(Segment[C, W], W, ListP2) → ListS2
12. Zip(Segment[A, Z], Z, ListP) → ListS
