多边形面积分割的几何作图法

Dividing Polygon Area by Geometric Drawing

利用同底等高（或等底同高）的三角形面积相等的原理，通过几何作图方法，把不规则平面条边形面积分割问题转换为三角形面积分割问题，从而实现分割点在周边任意位置处的不规则多边形的面积分割。

This article is mainly based on this principle: triangles with the same base and equal height are equal in area. We can transform the area dividing problem of irregular polygon into that of triangles by geometric drawing and in this way, it is possible to divide the area at any division point on its side.
