GeoGebra 命令及参数

1. Polygon(A, B, 4) → çokgen1, f, g, h, i, C, D
2. Rotate(çokgen1, (-(60°)), A) → çokgen1'
3. Polygon(E, F, G) → çokgen2, g_1, e, f_1
4. Dilate(E, 2, H) → E'
5. Dilate(F, 2, H) → F'
6. Dilate(G, 2, H) → G'
7. Polygon(E', F', G') → çokgen2', g', e', f'
8. Segment(H, E) → j
9. Segment(E, E') → k
10. Segment(H, G) → l
11. Segment(G, G') → m
12. Segment(H, F) → n
13. Segment(F, F') → p
