棱柱是多面体中最简单的一种几何体,是直线和平面的延续和深化,它蕴含着丰富的点、线、面的位置关系,因而高考题常以棱柱为载体考查线面平行与垂直位置关系、空间角与距离、面积与体积等,因此必须正确把握棱柱的性质,特别是一些特殊棱柱(平行六面体、正四棱柱、长方体、正方体等)的性质 Prism is the simplest kind of geometric body in polyhedron. It is a continuation and intensification of the straight line and the plane. It contains a rich positional relationship of points, lines, and faces. Therefore, the entrance question often uses the prism as a carrier to examine the parallel and vertical position of the line face. , space angle and distance, area and volume, etc., so we must correctly grasp the nature of the prism, especially the nature of some special prisms (parallel hexahedron, regular quadrangular prism, rectangular parallelepiped, cube, etc.)
