线段的中点是一个比较特殊的点,初中几何中的很多知识点都是以此为基础展开的,如三角形的中线、垂直平分线、中位线等等.因此,中点的应用十分广泛,解答与之有关的试题的灵活性也很强,同时,这也是深受命题者青睐的原因所在.所以,探究、分析和解决与线 The midpoint of the line segment is a rather special point, and many of the knowledge points in the geometry of the junior middle school are based on this, such as the triangular midline, the vertical bisector, the median line, etc. Therefore, the midpoint is widely used , The answers to the questions related to them are also very flexible, and at the same time, they are also the reason favored by the proponents. Therefore, exploring, analyzing and resolving the problems
