同学们,近期我们学习了长方体、正方体的相关知识,感受到了立体图形的神奇,也体会到这方面知识深奥。在实际问题的思考和解析中,需要我们学会缜密思考,全面理解立体图形的核心基本点:点、线、面、体的构造,促进我们的透彻理解和灵活运用,加速我们的领悟程度,也可以有效地避免一些不必要的错误。一、解读清“点”理解点的构造不能只靠记忆,而是通过具体的实物来强化我们的理解,让我 Students, we recently learned the cuboid, cube-related knowledge, feel the magic of three-dimensional graphics, but also to understand this profound knowledge. In the thinking and analysis of practical problems, we need to learn to think carefully and comprehensively understand the core basic points of stereoscopic graphics: the construction of points, lines, planes and bodies, to promote our thorough understanding and flexible application, to speed up our understanding, Can effectively avoid some unnecessary mistakes. First, the interpretation of clear “point ” to understand the point of the structure can not rely on memory, but through specific physical to strengthen our understanding, let me
