高中数学当中的几何知识就是根据已知条件以及图形对几何数量关系进行分析。在部分几何题型当中,相关的数量关系不会通过图形直接表示出来,而是要求学生根据已知条件画出辅助线,以此对几何问题进行解答,所以通过几何辅助线能够将几何数量之间的关系直观表示出来,提高学生解题的效率。在这样的背景之下,本文主要对辅助线在高中几何题型解答过程中的具体运用以及作用进行了分析,以此提高学生成绩的提高。
The geometry of high school mathematics is based on the known conditions and the geometry of the relationship between the number of graphs. In some of the geometry questions, the related quantitative relationship is not directly expressed by the graph. Instead, the students are asked to draw the auxiliary line according to the known conditions so as to solve the geometric problem. Therefore, by means of the geometric auxiliary line, the geometric quantity The relationship between the intuitively expressed to improve the efficiency of student problem solving. In this context, this article mainly analyzes the specific application and function of the auxiliary line in the process of answering high school geometry questions to improve the students’ performance.
