三视图是高考的新增内容,也是近年高考数学中的热点问题,且试题多数是三视图的逆向问题,即由题中给出的三视图,求三视图与立体几何中有关的证明计算问题,这一考查已成为高考命题的新热点,如面积、体积、空间距离、空间角的计算,平行、垂直的证明等,以考查学生的运算能力、空间想象能力和推理论证能力。
Three views of the college entrance examination is the new content, but also in recent years entrance exam math in the hot issues, and most of the questions are the reverse view of the three views, that is given by the title of the three views, seeking three views and three-dimensional geometry related to the proof of calculation This examination has become a new hot topic in college entrance examination proposition, such as area, volume, space distance, space angle calculation, parallel, vertical proof, in order to examine students’ computing ability, spatial imagination ability and reasoning demonstration ability.
