多边形立体几何几何作图

①本范例演示正方锥体的三维形态与结构；②涉及的核心数学概念包括立体几何、多边形、棱锥体积计算；③作图要点：使用Polygon命令构建底面，Pyramid命令生成锥体，Net命令展示展开图，PointIn命令实现点与面的交互；④适合高中立体几何教学与初学者空间想象能力培养。

GeoGebra 命令及参数

Polygon(A, B, 4) → poly1, f, g, h, i, C, D
Pyramid(poly1, b) → c, F, faceABF_1, faceBCF, faceCDF, faceADF, edgeAF, edgeBF, edgeCF, edgeDF
Net(c, a) → d, E, faceEGJ, faceGHK, faceHIL, faceEIM, edgeEG, edgeGH, edgeHI, edgeEI, edgeEJ, edgeGJ, G, edgeGK, edgeHK, edgeHL, edgeIL, edgeIM, edgeEM, H, I, J, K, L, M, faceEGHI
Pyramid(faceABF_1, B) → e, faceABB, faceBBF, faceABF, f, edgeBB, edgeBF
PointIn(faceHIL) → PointfaceHIL
PointIn(faceGHK) → PointfaceGHK
PointIn(faceEGHI) → PointfaceEGHI
PointIn(faceEIM) → PointfaceEIM
PointIn(faceEGJ) → PointfaceEGJ
