通过面积估算除法

GeoGebra 命令及参数

1. Random(5, 10) → bigL
2. Random(5, 10) → bigW
3. Polygon(A, B, C, D) → big, a, b, c, d
4. Random(100, 999) → bigVal
5. Random(10, 99) → smallVal
6. Polygon(E, F, G, H) → small, e, f, g, h
7. If(abs(correctsize - small) / correctsize < 1, abs(correctsize - small) / correctsize, 1) → error
8. Segment(L, M) → i
9. Segment(L, N) → j
10. Segment(L, O) → k
11. If(small < correctsize, "too small", "too big") → size
12. Polygon(J, K, P, Q) → poly1, j_1, k_1, p, q
13. Segment(R, S) → l
14. Polygon(EG, FG, GG, HG) → ghost, eg, fg, gg, hg
15. Textfield(divguess) → inputBox1
16. If(diverror < 0.6, "Pretty good estimate!", "Not a great estimate") → quality
