几何证明题是平面几何教学中的难点。这是因为几何题千变万化,一般没有明显的证题规律可循。为了便于学生掌握知识,引导学生探索证题途径,适当给以知识归类,熟悉一些证题的基本方法,是很有必要的。为此,我们试从如下三个方面谈几点证题体会。一、学会分析综合方法,打好几何证题基础。几何证明题,一般需要根据题设进行分析,从分析中寻找证题途径,用综合法书写证明过程。所谓分析,就是从“未知”看“需知”,逐步追朔到“已知”;所谓“综合”、就是从“已 Geometry proving is a difficult point in plane geometry teaching. This is because geometric problems are ever-changing, and generally there is no obvious rule of evidence. In order to make it easier for students to acquire knowledge, guide students to explore the ways of testimony, properly classify knowledge, and familiarize themselves with the basic methods of some test questions, it is necessary. To this end, we try to discuss several witness questions from the following three aspects. First, learn to analyze comprehensive methods and lay the foundation for geometrical testimony. Geometric proofs generally need to be analyzed according to the questions, find the way for the questions from the analysis, and use the comprehensive method to write the proof process. The so-called analysis is to look at “needs to know” from the “unknown” and gradually to “know”; the so-called “comprehensive” is from "has been
