摘要
在合同变换的一般定义下,探讨了合同变换所包括的平移变换、旋转变换、轴反射变换的定义及其在不同题型中的具体使用方法.给出了不同类型的初等几何问题适用的具体变换,对解决初等几何问题提供了一定参考方法.
Under the general definition of congruent transformation,this paper explores the definitions of translation transformation,rotation transformation,and axial reflection transformation included in congruent transformation and their specific applications in different types of problems in detail.Through the analysis,several specific transformations applicable to different types of elementary geometry problems are given.The results provide some valuable methods for the research of other elementary geometry problems.
