①本范例演示了如何通过 GeoGebra 动态构造角平分线;②涉及的核心数学概念包括角、线段、旋转对称性;③作图要点——使用了 Point(点)、Rotate(旋转)、Angle(角度)、Segment(线段)、Ray(射线)等 GeoGebra 命令与对象α、A、B、B'、β、f、g、h、i;④适合初中及以上学生学习和理解几何作图方法,可用于数学教学演示。
GeoGebra 命令及参数
Point(xAxis) → ARotate(B, α, A) → B'Angle(B, A, B') → βSegment(A, B) → fRay(A, B') → gRay(A, B') → hRay(A, B) → i
AI 绘图提示语参考
绘制一个角平分线的动态构造。首先在x轴上创建点A,然后围绕A点旋转点B得到B',接着画出角BAB',并构造角的两边AB和AB'的射线,最后画出角BAB'的角平分线。
以上提示语为根据原始绘图命令整理而来,仅供参考。
