学习几何,主要是应用几何定义、公理、定理去论证和解答几何题.但在具体应用几何知识时,往往不是运用文字表述的语言去推理,而是运用几何符号语言去推理.可以这样说:几何符号语言是我们证明、解答几何题的纽带.因为几何解题的过程和结果都要用语言文字和符号表达出来,所以阅读和表达是几何中的一个重要问题.这个问题之所以显得突出,是因为它不仅是一般的语言文字的问题,还是带着学科特点的问题.例如,延长线段可以向两个方向延长,要用一般的语言把这个
Learning geometry, the main application of geometric definitions, axioms, theorems to demonstrate and solve the problem of geometry.But in the specific application of geometric knowledge, it is often not to use language to describe the language to reason, but the use of geometric language to infer reasoning.That can be said: Geometry symbolic language is our link in proving and answering geometry problems. Since the process and the result of geometric problem solving are both expressed in languages and symbols, reading and expressing are important issues in geometry. The reason why this problem stands out is that, Because it is not only a question of general language but also of a subject matter, for example the extension of an extension of a line can be extended in both directions by using the usual language
