多数平面几何题都无法直接证明,需要借助辅助线才能够证明。特别是一些中考题,几乎每个平面几何题的证明都要通过添加辅助线来解答。添加辅助线是解平面几何题的难点,因此在课堂上,教师需要针对添加辅助线的方法进行介绍,同时通过例题来验证这些方法,由此培养学生的思维能力,提高教学效率。1与三角形有关的辅助线添法在几何证明题中,综合法一般是最为普遍的解题方法,从现有的条件入手,按照已知的定理等,逐步推理,最终证明结论成立。当遇到一些较为复杂的题目 Most of the plane geometry problems can not be directly proved, you need to help line to prove. In particular, some senior high school entrance examination questions, almost every proof of plane geometry questions should be added by adding aids to answer. Therefore, in the classroom, teachers need to introduce methods of adding auxiliary lines and validate them through examples to cultivate students’ thinking ability and improve teaching efficiency. A triangle-related auxiliary Tim addition method In the geometric proof, the synthesis method is generally the most common solution to the problem, starting from the existing conditions, according to the known theorem, and so on, and ultimately prove that the conclusion holds. When faced with some of the more complex issues
