《数学课程标准》要求学生所掌握的空间与图形内容如下:能够借助不同的方法探索几何对象的有关性质;能够使用不同的方式表达几何对象的大小、位置与特征;能够在头脑里构建几何对象,进行几何图形的分解与组合,能够对某些图形进行简单的变换;能够借助数学证明的方法确认数学命题的正确性。图形与证明是空间与图形的核心内容之一,课标要求学生掌握基
Mathematical Curriculum Standards require that students have space and graphic content as follows: to explore the relevant properties of geometric objects in different ways; to be able to express the size, position and characteristics of geometric objects in different ways; to construct geometrical objects in their minds , The decomposition and combination of geometric figures, some of the graphics can be a simple transformation; can confirm the correctness of mathematical propositions by means of mathematical proof. Graphics and certification is one of the core elements of space and graphics, curriculum requirements require students to master the base
