空间的距离分为点点、点线、点面、线线、线面、面面以及曲面上两点的距离等几种 ,其中线线、线面、面面的距离往往相互转化 ,最终转化为点面间的距离 .一、基础知识1 .对于空间距离 ,我们主要研究异面直线的距离、点到平面的距离、直线和平面的距离以及两个平行平面的距离 .其 The distance of space is divided into several types: point, dotted, point, line, line, face, and the distance between two points on the surface, among which the distances of line, line, and surface are often transformed into each other, and finally they are converted into The distance between points. First, the basic knowledge 1. For the space distance, we mainly study the distance of the straight line from different sides, the distance from the point to the plane, the distance from the straight line and the plane, and the distance from two parallel planes.
