求两条异面直线的距离是高中立体几何的重点也是难点知识,遇到求两条异面直线的距离问题,许多学生往往感到比较困难,常常无从下手,而且大多对于寻求异面直线公垂线段感到无所适从,解答此类问题,主要的方法有“定义法”和“转化法”,特别是转化的思想技巧性强,有利于培养学生的? Finding the distance between two different straight lines is the key and difficult point of high school’s three-dimensional geometry. When we encounter the problem of finding the distance between two different straight lines, many students often find it difficult and often have no way to start, and most of them are looking for straight lines. The line segment feels at a loss. The main methods for answering such questions are the “definition method” and the “transformation method.” In particular, the transformation has strong ideological skills and is conducive to cultivating students.
