我们知道,所谓证明,就是借助于一些其真实性已经证明了的命题(公理、定理、定义等)按照逻辑方法来判断某个命题成立的过程,也就是揭示题设与结论之间的逻辑关系的过程。在证题中所引用的那些命题就好比建立这个逻辑关系的“链条”中的各个“链环”,这些命题中贯穿于整个学科的主要是定理,它既揭示了本学科所研究的客观规律,又为阐明以后的理论提供了根据。因此,如何引用定理就成为解决几何证明题的关键。 We know that the so-called proof is the process of judging the establishment of a certain proposition by means of logical propositions (axioms, theorems, definitions, etc.) that have been proved by their authenticity, that is, revealing the logical relationship between the questions and conclusions. the process of. The propositions quoted in the testimony are analogous to the “chains” in the “chain” that established this logical relationship. The main theorem throughout these disciplines is the theorem, which not only reveals the objective laws studied by the subject. It also provided the basis for clarifying the later theory. Therefore, how to cite the theorem becomes the key to solving the geometric proof.
