GeoGebra goes 3D
①本范例演示立方体的经典展开图，即如何将三维立方体展开成二维平面图形；②涉及的核心数学概念包括多边形、立体几何、几何作图；③作图要点——从下方『构造摘要』提炼用到了GeoGebra命令/对象：Cube（立方体）、Net（展开图）、点A,B,a,C,D,E,F,G,H、面faceABCD,faceADHE,faceABFE,faceBCGF,faceCDHG,faceEFGH、边edgeAD,edgeAB,edgeBC,edgeCD,edgeAE,edgeDH,edgeEH,edgeEF,edgeBF,edgeFG,edgeCG,edgeGH、点b,c,I,J,K,L,M,N,O,P,Q,R,S；④适合初中及以上学段学习立体几何、几何作图，或用于数学教学演示。
