三角形的中线与三角形全等的判定

The Judgement of The Mean Line and Fully Equivalent of the Triangle

用初等几何计算的方法研究了三角形的中线与三角形全等的判定问题,得到了三个判定 定理。解决了三角形中线与三角形全等的判定和几何作图中利用中线作三角形的唯一性问题。

in this paper , the problem of the judgements of the mean line and fully equivalent of the triangle are discussed by use the methods of geometry calculation, some judgement theorems are obtained.
