多边形立体几何几何作图

这个范例演示了棱锥的展开图。涉及的核心数学概念包括立体几何中的棱锥结构。通过使用GeoGebra命令如Intersect、Polygon等，可以构造棱锥的各个面。适合初中及以上学生学习立体几何。

GeoGebra 命令及参数

Intersect(xAxis, yAxis) → A
Polygon(A, B, n) → poly1, a, k, l, m, C, D, E, F, G, H, I, b, J, K, L, c, d, e, f, g, i, j
Pyramid(poly1, h) → o, M, faceIJM, faceJKM, faceKLM, faceALM, edgeAM, edgeBM, edgeCM, edgeDM, edgeEM, edgeFM, faceABM, edgeGM, edgeHM, edgeIM, edgeJM, edgeKM, edgeLM, faceBCM, faceCDM, faceDEM, faceEFM, faceFGM, faceGHM, faceHIM
