代沙格定理逆定理的一种证明方法

The Prove of Euler Line in the Higher Geometry

三角形的外心、重心、垂心位于同一条直线上,这条直线称为欧拉线。文章证明了高等几何中代沙格定理的逆定理,并用其证明了欧拉线,比初等几何证明方法更简便。

Triangle circumcenter,center of gravity,orthocenter located in the same line,the line we called the Euler line.In This paper,I proved the converse theorem of Desargues in the geometry of higher,and using it proved the Euler line,easier than the methods of elementary geometry.
