在高中数学学习中,几何问题是整体数学中分数占比很大的一部分,其在高考的解答题部分,六道题中便有两道为几何题,因此学好高中数学就必须学好数学几何。在高中数学几何解题之中画出辅助线是一种极其常见的解题方式,正确合理的画出辅助可以有效的让题目的条件更为明显化,同时也会在很大程度上降低解题的难度,故此教师在教学中帮助学生掌握高中数学几何辅助线的作法是十分必要的。在此背景下,文章首先介绍了高中数学几何题的特点,进而具体分析了辅助线在高中数学几何题中的重要作用。
In high school mathematics learning, the geometry problem is a large part of the overall mathematics scores, and its answer questions in the college entrance examination part, there are two questions in six questions for the geometry, so to learn high school mathematics, we must learn math geometry. It is an extremely common way to figure out the auxiliary line in the high school mathematical geometry problem solving. The correct and reasonable auxiliary drawing can effectively make the conditions of the question more obvious and reduce the solution to a great extent The difficulty of the question, so the teacher in teaching to help students master high school mathematical geometry line is very necessary. In this context, the article first introduced the characteristics of high school mathematics geometry, and then analyzed the important role of the auxiliary line in high school mathematics geometry.
