函数几何作图滑块动画
这是一个滑动展示，让学生了解存在哪些数学领域的示例。通过旋转文本和几何作图，展示了多个数学概念。使用了Intersect、Point、Polygon、Element、RotateText等命令。适合初中及以上学生，用于数学概念的直观教学。

AI 绘图提示语参考

画一个直角坐标系，交点为A。在x轴上取点B。以A、B、C为顶点画一个三角形。从单词列表中依次取出第一个单词，旋转60度和-60度得到两个新单词。找到A、B的中点D，画一条线段DE。在线段DE上取点F和G，画线段FG。从单词列表中依次取出第二个到第七个单词。绘制一个笔触路径，路径由一系列坐标点组成。
以上提示语为根据原始绘图命令整理而来，仅供参考。
