圆多边形角概率统计几何作图
所属专题 Simplifying Radicals: Geometric Thin Slice
这个范例通过几何作图与变换，把多个几何要素（多边形、圆与角等）“拼合”成可观察的度量关系，并与统计展示中的中位数思想相呼应。核心数学概念包括勾股定理（用于建立长度与直角关系）、三角函数（体现正弦相关的角度—边关系）、中位数与理性数的可计算刻画，以及箱线图中常见的分位度量思想。作图要点体现在：用 Polygon、Segment 构成多边形与线段，用 Line、Point 生成基准点与直线；用 Circle、Intersect 处理圆的交点与约束几何位置；用 OrthogonalLine 建立垂线/直角结构，并结合 Angle 描述关键角；通过 Midpoint、Vector、Rotate、RotateText、Dilate、Translate 完成点/向量的定位、旋转、缩放与平移，使几何关系在不同位置上保持结构一致。对象列表中的 A、B、C、t1 等点与 I、J、K、F、G、H 等派生对象，体现了从基础几何到度量/分组展示的逐步组合。适合中学数学（几何与函数综合）以及数学建模与数据可视化入门课堂使用。

AI 绘图提示语参考

请绘制一个由多个正方形和圆组成的几何图形。图形从左到右依次排列，每个正方形旁边有一个半径为1的圆。正方形和圆通过垂直线连接，形成一个阶梯状的结构。图形中包含一个起点A，从A出发依次连接各个正方形和圆的顶点，最后形成一个封闭的路径。图形整体呈现对称性，适合用于几何和统计的教学演示。
