近些年,棱柱、棱锥和球等空间几何体一直是高考的热点.试题被设计为客观题时,往往考查这些几何体的基本概念、性质以及简单的计算;试题被设计为解答题时,主要是以这些几何体中的某一个或几个几何体为载体,着重考查直线与平面的位置关系、球与多面体的组合以及空间角、距离、面积、体积的计算等.本来,如果学生具有很好的空间想象力、具有空间转化平面的能力、熟练掌握了几何语言并且
In recent years, spatial geometry such as prisms, pyramids, and spheres has always been a hot spot for college entrance examination. When questions are designed as objective questions, they often examine the basic concepts, properties, and simple calculations of these geometry; when questions are designed to solve questions, they are mainly Using one or more of these geometry as a vector, we examine the positional relationship between lines and planes, the combination of spheres and polyhedrons, and the calculations of spatial angles, distances, areas, volumes, etc. Originally, if students had a good space Imagination, ability to have a spatial transformation plane, mastery of geometric language and
