摘要
文章介绍了高等几何中交比,调和比的定义及其相关性质定理,并利用高等几何中的调和性解决了一些初等几何中的具体问题,充分体现运用调和性去解决初等几何问题的优越性与新颖性,也表明了高等几何与初等几何的密切联系。
The paper introduces the definition and related theorem of the cross ratio and the harmonic ratio of Higher Geometry.Some practical questions of Elementary Geometry have been solved by the Harmonicity of Higher Geometry which shows the new advantageous approaches to solve the questions of Elementary Geometry by using it as well as the close relationship between Higher Geometry and Elementary Geometry.
