等边三角形阵列

GeoGebra 命令及参数

1. Polygon(A, B, 3) → poly1, a, b, c, C
2. Point(a) → D
3. Vector(C, D) → u
4. Translate(poly1, u) → poly1'
5. Rotate(u, 60*°, C) → v
6. Translate(poly1, v) → poly1'_1
7. Sequence(Translate[Sequence[Translate[poly1, Vector[(n * u)]], n, -10, 10], Vector[(m * v)]], m, -10, 10) → list1
8. Translate(A, w) → A'
9. Translate(B, Vector[(-v)]) → B'
10. Polygon(D, A', B') → poly2, b', d, a'
11. Sequence(Translate[Sequence[Polygon[Translate[D, Vector[(n * u)]], Translate[A', Vector[(n * u)]], Translate[B', Vector[(n * u)]]], n, -10, 10], Vector[(m * v)]], m, -10, 10) → list2
