GeoGebra 命令及参数

1. Random(-10, 10) → a
2. Random(-10, 10) → b
3. If(a < 0, (-a), a) → p1
4. If(b < 0, (-b), b) → p2
5. Sequence(Circle[A + ((2 * i) + 1, 0), 0.9], i, 0, p1 - 1) → l1
6. Sequence(Circle[(0, -1) + ((2 * i) + 1, 0), 0.9], i, 0, p2 - 1) → l2
7. Min(p1, p2) → d
8. Point(yAxis) → B
9. Point(yAxis) → E
10. Sequence(Polygon[B + ((2 * i), 0), C + ((2 * i), 0), D + ((2 * i), 0), E + ((2 * i), 0)], i, 0, d - 1) → l5
11. Textfield(text1) → InputBox1
12. If(text1 ≟ text2, "Excellent", "Try again") → text3
13. Circle(F, 2) → e
14. Point(e) → G
15. Rotate(G, α, F) → G'
16. Angle(G, F, G') → β
17. CircleSector(F, G, G') → f
