多边形立体几何几何作图
①本范例演示立方体的展开图及其动态变化过程；②涉及的核心数学概念包括多边形、立体几何、变换；③作图要点提炼自构造摘要，使用了Point、Segment、Polygon、Circle、Line、Intersect、Rotate、OrthogonalLine、CircleArc、Vector、Translate、Ray、LineBisector、If、Midpoint等GeoGebra命令与对象；④适合高中阶段学生学习和理解立体几何的展开与折叠特性，也可用于相关课题的演示教学。

AI 绘图提示语参考

绘制一个立方体的展开图，并动态展示其几何变换。首先绘制一个正方形，然后围绕一个顶点旋转并连接相邻的顶点，形成展开图的各个面。接着，通过旋转和移动，展示展开图的各个面之间的关系，最终形成一个动态的立方体展开图。
以上提示语为根据原始绘图命令整理而来，仅供参考。
