确定组合几何体的三视图需要一定的空间想象力,是今后学习立体几何的基础.这类题已成为中考命题的热点.解这类题,除熟悉常见的单个几何体从不同方向看得到平面图形外,还需考虑各个几何体的位置关系.
Determine the combined geometry of the three views need some space imagination is the basis for the future study of solid geometry .This type of question has become a hot topic in the test. Solutions to these questions, except familiar with a single geometry from different directions to see the plane outside , Also need to consider the location of the relationship between the geometry.
