立体几何试题由于线面关系复杂,学生往往感到畏惧.而正方体由于图形对称完美,具有其他图形难以企及的性质,如果能挖掘题设条件,展开联想,构造出相应的正方体,其特性即可得到充分利用,使解题过程简捷明快,生动有趣.本文谈谈利用正方体的性质构造正方体的思维策略.1利用几何体可 Due to the complex surface-line geometry, students often feel daunting.Due to the symmetry of the perfect symmetry of the cube, with other graphics difficult to match the nature, if you can tap the design conditions, expand the association, the structure of the corresponding cube, its characteristics can be obtained Make full use of, to make the problem solving process simple, lively and interesting.This article talk about the use of the nature of the cube structure of the cube thinking strategy.1 The use of geometry
