多边形立体几何几何作图

所属专题 Chapter 11: Surface Area and Volume

这个范例演示了棱柱的展开图。涉及的核心数学概念包括几何、棱柱和四边形。通过使用GeoGebra命令如Intersect、Point、Prism、Net等，可以构造棱柱的各个面和边。适合初中及以上学生学习几何作图。

GeoGebra 命令及参数

Intersect(xAxis, yAxis) → A
Point(zAxis) → B
Point(yAxis) → D
Point(xAxis) → H
Prism(A, B, C, D, H) → a, E, edgeAB, edgeBC, edgeCD, edgeAD, edgeAH, edgeBE, edgeCF, edgeDG, edgeEH, edgeEF, F, edgeFG, edgeGH, G, faceABCD, faceABEH, faceBCFE, faceCDGF, faceADGH, faceEFGH
Net(a, b) → c, I, R, S, T, U, V, faceIJKL, faceIJNM, faceJKPO, faceKLRQ, faceILST, J, faceMNUV, edgeIJ, edgeJK, edgeKL, edgeIL, edgeIM, edgeMN, edgeJN, edgeJO, edgeOP, K, edgeKP, edgeKQ, edgeQR, edgeLR, edgeLS, edgeST, edgeIT, edgeNU, edgeUV, edgeMV, L, M, N, O, P, Q
Segment(O, K) → d
Midpoint(O, C) → W
Midpoint(Q, R) → Z
