两点之间线段最短是平面几何中一个重要的公理,应用这一公理可以解决许多几何作图和现实生活中最短路程的问题.以下举几例予以解答,以期对同学们有所启发. The shortest line segment between two points is an important axiom in plane geometry. Applying this axiom can solve the problem of many geometry mapping and the shortest distance in real life. Here are some examples to be answered in order to inspire the students.
