说到美很多人联想到的或许是肤若凝脂、明眸皓齿的女子;或许是典雅秀逸、笔墨华滋的山画。很少有人将美之词赋予我们的数学。但细心的人会发现美在我们数学之中有着他独特之处。对称性是自然界存在的一个普遍的现象。正因为对称性的普遍性和重要性,我们初中阶段引入了图形的对称性,通过它来研究我们生活中的对称性。“对称”不仅是中学数学内容中一个重要的概念,更是一种重要的思想方法。在“对称”中往往体现出数学 When it comes to the beauty of the United States, many people think that if the skin if creamy, bright eyes white teeth woman; perhaps elegant elegant, pen and ink Huashan painting. Few people give beauty to our math. But attentive people will find that beauty has something unique in our mathematics. Symmetry is a common phenomenon in nature. It is precisely because of the universality and importance of symmetry that we introduced the symmetry of the figure in the middle school stage to study the symmetry in our life. “Symmetry ” is not only an important concept in secondary school mathematics, but also an important way of thinking. In “symmetry ” often reflects mathematics
