《证明》这章主要学习定义、命题、定理、推论以及原命题及其逆命题、互逆命题等概念,并且要求知道证明的意义和证明的必要性,能从基本事实出发,体会通过合情推理探索数学结论、运用演绎推理加以证明的过程,本章的学习对于学生学好几何内容,培养合情推理与演绎推理的能力有很大的帮助.为了帮助同学们学好这一章,本文对证明中的几个难点作以解读. This section of “Proof” mainly studies concepts such as definitions, propositions, theorems, inferences, original propositions and their contradictory propositions, reciprocal propositions, and the like, as well as the need to know the significance of the proofs and proofs. From the basic facts, Reasoning to explore mathematical conclusions, the use of deductive reasoning to prove the process of learning this chapter for students to learn geometry content, to develop sympathy and deductive reasoning ability is very helpful in order to help students learn this chapter, Several difficult to interpret.
