在高中数学立体几何中,空间角通常指的是异面直线所成的角、直线和平面所成的角及二面角的平面角,能比较集中反映空间想象能力的要求,它是空间图形的一个要素,反映了对空间主元线线、线面、面面关系的深入认识和理解,其求解思路是把几何图形的问题转化成了可计算、可量化的数学问题,使我们对空间角有了更具体、更精确的认识。求解问题时所体现出来的平移,构角、解三角形,甚至建系、数形结合等思想,可以说是高中数学思想的一个集中体
In high school mathematics solid geometry, the spatial angle usually refers to the angle formed by a straight line of a straight line, the angle formed by a straight line and a plane, and the plane angle of a dihedral angle, which can more closely reflect the requirement of space imagination. It is a space graph , Which reflects the deep understanding and understanding of the line, line surface and surface relationship of the main line of the space. The solution is to convert the geometric problem into a computable and quantifiable mathematical problem, Angle with a more specific, more accurate understanding. The problems of translation, corner formation, solution of triangles, and even the establishment of lines and figures and other ideas can be said to be a focus of high school mathematics
