图形变换是一种等价变形,在解决某些数学问题时,若能根据题设条件,将一般问题的图形转化为特殊的图形来处理,不仅能激发学生的探索欲望和创新意识,而且还可把抽象的问题具体化,复杂的问题简单化,有利于学生数学素养的提高。本文将介绍几种实用的方法。
Graphic transformation is a kind of equivalent deformation, in solving some mathematical problems, if the conditions can be based on the general problem of graphics into special graphics to deal with, not only can stimulate students’ desire for exploration and innovative awareness, but also Can abstract the problem of specific, complex problems simplistic, is conducive to improving students’ mathematical quality. This article will introduce several practical methods.
