一、背景立体几何是每年高考必考内容之一,分值占到高考数学整张卷面12%左右,因此要在高考数学中取得较好的分数,立体几何的地位就不能够不引起重视了.以江苏省高考为例,一般安排一道填空题考察空间位置关系的判断,一道大题考察空间位置的证明,份量还是比较重的.这就要求我们从高考一轮复习开始,对立体几何要给与高度的关注,不 First, the background of the three-dimensional geometric geometry of the college entrance examination will be one of the content, the score accounted for the college entrance examination math overall volume around 12%, so to get a better score in college entrance examination mathematics, the status of three-dimensional geometry can not be ignored Take the college entrance examination in Jiangsu Province as an example, the general arrangements for a blank fill inspected space to determine the location of the relationship between a major problem of space location to prove that the weight is still relatively heavy.This requires us to review the beginning of a round of college entrance examination, the three-dimensional geometry To give a high degree of attention, no
