摘 要:初等几何变换是解决实际问题的杠杆.在几何的解题过程中,当题中所给的条件不够明显时,我们常常要运用初等几何变换里的平移、旋转、对称和位似找到题中的不变量,解决问题.本文简述初等几何变换的主要内容,并通过具体的解题过程介绍了它常见的几个变换及其应用.利用具体的典型的例题介绍了这些变换的不同.37647 毕业论文关键词:初等几何变换;中学数学;应用
Elementary Geometric Transformation in Middle School
Mathematics And Its Application
Abstract: Elementary geometry transform is leveraged to solve practical problems. In the geometry of the problem solving process, when the questions given in the conditions of not enough obvious, we often need to use the translation, rotation, symmetry in the elementary geometry transform and find the problem of invariant, solve the problem. In this paper, through the study of higher mathematics and advanced algebra, etc, and on the basis of fully understand the relevant concepts, briefly describes the main content of the elementary geometry transform, through specific problem solving process introduces its common several transformation and its application. Using specific typical examples, introduced the transformation of different.
Key words: Elementary geometric transformation;Middle school mathematics; the application of problem solving
