笔者已经介绍初中数学竞赛有关代数常用的一些解题方法,下面介绍解平面几何的一些方法和技巧,谨供参考。一、综合法这种方法是从已知条件入手,根据学过的概念,法则,公理和定理等,逐步进行推理,探索由这些已知条件可以推导出哪些结论,再由这些结论推导出新的结 The author has already introduced some problem solving methods commonly used by algebra in junior high school mathematics competitions. Here are some methods and techniques for solving plane geometry. First, the synthesis method This method is based on known conditions. Based on learned concepts, rules, axioms and theorems, etc., the reasoning is gradually carried out to explore which conclusions can be deduced from these known conditions, and then these conclusions can be derived.
