立体几何中图形的位置关系可用。描述性语言表示,还可以用数值定量表示,“空间角”和“空间距离”就是表示图形位置关系的数量。历年全国高考试题中都有涉及到这两个数值的问题。本文就涉及到求空间角的高考题及解法作分析,供同学们复习时参考。
The positional relationship of the graphics in the solid geometry can be used. Descriptive language can also be expressed quantitatively. “Spatial angle” and “Spatial distance” are the number of graphical position relationships. There have been problems involving these two values in the national examination questions over the years. This article involves the analysis of the college entrance examination questions and solutions for the spatial angle, for reference when the students review.
