《轴对称图形》一章是初中数学非常重要的内容,其中的很多知识点都经常出现在中考当中.这章是在小学阶段初步认识轴对称图形的基础上对轴对称图形更深层次的学习(内容相对来说更加抽象,对学生逻辑思维能力的要求有所提高,已经从生活中的轴对称图形过渡到了数学中的轴对称图形).本文从创设情境、联系生活实际
The chapter “Axisymmetrical Graphs” is a very important part of junior high school mathematics. Many of these knowledge points often appear in the middle school exams. This chapter is based on a preliminary understanding of axisymmetric patterns in elementary school and a deeper understanding of axisymmetric patterns ( The content is relatively more abstract, the requirements for students’ logical thinking ability have been improved, and the transition from the axially symmetric figure in life to the axially symmetrical figure in mathematics has been made. This article establishes the situation and links with the reality of life.
