本刊曾于85年第1l期刊登过李琴堂同志“提高初中学生解题速度的几点做法”的文章,读后颇受启发,但是,它仅涉及代数有关问题,不很全面,本文试从几何的角度也来谈谈这个问题,权且作为对“李文”的补充。平面几何,是中学数学的一个重要组成部分,而证明又是平面几何的核心内容,初中学生对于几何证明题,往往束手无策,找不到解题的门路。对于需添 This article was published in the 1st issue of the 85th issue of Comrade Li Qintang’s article “Improve the Speed ​​of Problem Solving for Junior Middle School Students”. After reading it, I was inspired. However, it only deals with algebra-related issues. It is not very comprehensive. From the perspective of geometry, we can also talk about this issue, and the right is also a supplement to “Li Wen.” Plane geometry is an important part of middle school mathematics, and proof is the core content of plane geometry. Junior high school students often have no way to solve the problem of geometric proof, and can’t find a solution to the problem. For the need to add
