数学是一个严密的逻辑体系,其中的定理、命题是经过历史的不断推进发展而日趋成熟的,要证明这些命题、定理,就必须明确其中的概念.概念是命题的基本组成单元,是数学的重要组成部分,是学习过程中不可跳跃的阶梯.而图形与几何作为数学的一个专题,是对空间图形本质的研究.我们生活在形形色色的物质世界中,从中抽象出的形状各异的几何体成为了数学学习的一个重要部分,与之相关的概念是进一步学习的基础.比
Mathematics is a rigorous logic system, in which the theorems and propositions are matured through the continuous development of history. To prove these propositions and theorems, the concepts in them must be clearly defined. Concept is the basic unit of proposition, Is an important part of the learning process can not jump ladder.And graphics and geometry as a topic of mathematics, is the study of the nature of space graphics.We live in a variety of material world, abstracted from the geometry of different shapes become An important part of mathematical learning, the concepts associated with it are the basis for further study.
