浅谈对称性在中学数学解题中的应用

AbstractSymmetry is an important module in middle school mathematics learning and animportant thought method.Symmetry is an important breakthrough in the process ofsolving problems.Using symmetry can simplify the problem,make the problemsystem clear,and can be simplified.On the basis of previous studies,this paper makesa systematic summary and summary of the application of symmetry in solvingmathematical problems in middle schools.First of all,the concept of symmetry andits significance in three aspects are summarized;then,the expression of symmetry inmiddle school mathematics is summarized:symmetry of graphics,symmetry offormula,symmetry of theorem and symmetry of solving method;finally,the paperdiscusses separately Symmetry in junior high school mathematics and theapplication of high school mathematics problem solving,according to the type ofclassification and summary,and give examples to illustrate.Key words:Symmetry;Middle School Mathematics;Problem Solving Strategies;Problem Solving Skills2
