多边形函数立体几何

①本范例演示正方锥体的三维形态与结构；②涉及核心数学概念包括立体几何、多边形、函数图像、分片函数等；③构造要点运用了多边形(Polygon)、锥体(Pyramid)、网格(Net)、点在图形上(PointIn)等GeoGebra命令与对象；④适合高中立体几何教学与几何作图学习。

GeoGebra 命令及参数

Polygon(A, B, 4) → poly1, f, g, h, i, C, D
Pyramid(poly1, b) → c, F, faceABF, 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
PointIn(faceHIL) → PointfaceHIL
PointIn(faceEIM) → PointfaceEIM
PointIn(faceGHK) → PointfaceGHK
PointIn(faceEGHI) → PointfaceEGHI
PointIn(faceEGJ) → PointfaceEGJ
