平面几何中有许多命题,需要根据已知公理或定理,运用演绎推理的方式来判断其真实性,通常叫做证明题。对于几何证题,中学生往往感到困难,这主要是由于中学几何证题多数采用综合法,因定理较多,证法不一,不容易较快掌握证题的普遍规律;加之,近几年来,由于“四人帮”的干扰破坏,严重地削弱了中学几何证题的教学。如何进一步提高中学生的几何证题能力,已成为当前加强基础知识教学的一个重要课题。
There are many propositions in plane geometry. According to known axioms or theorems, deductive reasoning is used to judge its authenticity. It is usually called proving. For students with geometric test questions, middle school students often feel difficult. This is mainly due to the fact that most of the secondary school geometry test papers adopt a comprehensive method. Because there are many theorems, the evidence is not the same, and it is not easy to quickly grasp the general laws of the test questions. In addition, in recent years, Due to the disruption and disruption of the Gang of Four, the teaching of middle school geometry was severely weakened. How to further improve the ability of middle school students to testify the geometry has become an important topic in the current strengthening of basic knowledge teaching.
