一、引言几何图形的变化分类是数学学习的重要部分,初中学生对于几何图形的学习为以后的数学几何学习奠定了坚实的基础,也有利于解决日常生活中的很多问题。现今各地的考试中,对于图形与空间几何等进行综合出题的越来越多,本文对于初中数学的几何图形变化分类教学的意义以及案例进行分析与讨论,进一步研究几何图形形状、位置等的变化,加深对几何图形的认识,也是对已学知识进行复习与总结。二、几何图形变化分类教学的意义
I. INTRODUCTION The change of geometry is an important part of mathematics learning. The study of geometry for junior middle school students lays a solid foundation for future mathematical geometry study and also helps to solve many problems in daily life. Nowadays, there are more and more questions about the integration of graphics and space geometry in the examinations around the world. This paper analyzes and discusses the significance of classifying the geometry of junior high school mathematics and the case study, and further studies geometry shape and position Change, deepen the understanding of geometric figures, but also to learn the knowledge review and summary. Second, the classification of geometric changes in the significance of teaching
