空间几何蕴藏着丰富的数学思维方法和思想精髓,是学生创新思维的生长点.本文对空间几何问题的解题方法作一归纳总结,以期给读者一些有益的启示.1嵌入把被研究的图形嵌入到最熟悉、最常用的长方体(正方体)、正四面体中去,借助长方体、正四面体等几何模型,凸显研究图形中相关元素 Spatial geometry contains a wealth of mathematical thinking methods and ideological quintessence, which is the growth point of student’s creative thinking. This paper summarizes the problem solving methods of spatial geometric problems, in order to give the reader some useful inspiration.1 The graphics embedded in the study Embed in the most familiar and common cuboids (cubes), regular tetrahedrons, with the help of geometrical models such as cuboids and regular tetrahedrons to highlight the relevant elements in the study graphic
