Solid geometry, based on a number of axioms and concepts, focus on studying the natures of space graphics using logical reasoning. When deal with the problems of space graphics, such as vertical, parallel, distance and angle, through the different transformation of the graphics, strong skills is needed because of the great difficulties. So it is not easy for students to find the exact entry points. However, using vector methods in study solid geometry will achieve significant results. The Vector knowledge has a very important value and status in high school study, it has the advantages that can not replaced by traditional geometry knowledge and methods when deal with solid geometry problems. Mathematic textbook reform of high school introduced direction vector of the straight line and normal vector of the plane to the teaching process, which provided a very practical and convenient problem-solving tool for handling space problem of the solid geometry.
