立体几何主要研究空间几何体的位置关系和数量关系,是高中数学的重要组成部分.学业水平考试对立体几何中的基础知识,基本技能和方法进行了重点考查.从近几年的试题来看,基本保持一小题和一大题的格局,占10分左右.小题以考查三视图和空间几何体的表面积、体积为主,大题突出考查空间几何体的位置关系和数量关系,试题难度不大,容易得分.但一部分同学由于基础知识不扎实,空间想象能力薄弱,没有形成良好的空间观念,论证不严谨,丢分较多.本文与大家一起
Three-dimensional geometry is mainly study the spatial relationship between space geometry and the number of relations, is an important part of high school mathematics.Learning proficiency test on the three-dimensional geometry of the basic knowledge, basic skills and methods for a focused examination.From the test questions in recent years, The basic maintenance of a small problem and a big problem pattern, accounting for about 10. Small topic to examine the three views and spatial geometry of the surface area, the volume of the main problems highlight the spatial relationship between spatial geometry and quantitative relationship between the difficulty of the test , But easy to score.But some students because the basic knowledge is not solid, the space imagination is weak, did not form a good concept of space, the argument is not rigorous, dropped points more.
