GeoGebra 命令及参数

1. Point(Segment[(h + 1, y(C) + 10), (h + 1, y(C) - 10)]) → D
2. Line(A, B) → f
3. Vector(A, C) → u
4. Polygon(A, C, B) → t1, b, a_1, c
5. Segment(A, C) → h_{1}
6. Vector(C, D) → v
7. Vector((h, 0), A) → w
8. Vector((0, 0), (h, 0)) → j
9. RandomElement({-8, -7, -6, -5, -4, -3, -2, -1, 1, 2, 3, 4, 5, 6, 7, 8}) → n
10. Random(-8, 8) → o
11. Random(-8, 8) → p
12. If(h ≟ o, "Horizontal shift is correct!", "Horizontal shift is not correct.") → text9
13. If(n ≟ rise, "Vertical stretch is correct!", "Vertical stretch is not correct.") → text10
14. If(p ≟ y(A), "Vertical shift is correct!", "Vertical shift is not correct.") → text11
15. Textfield(s) → InputBox1
