中心对称图形在我们日常生活中 ,随处可见 根据“经过对称中心的直线将中心对称图形分成两个面积相等的部分” ,我们来看下面几个问题 :例 1　分别把下面的图形分成两个面积相等的部分 .图 1— 1　　分析　图中的矩形和圆都是中心对称图形 ,所以只要分别找出它们的对称中心 , In our daily life, the center symmetry pattern can be seen everywhere. According to “the center symmetry pattern is divided into two equal parts by the straight line passing through the center of symmetry”, we can see the following questions: Example 1 Separate the following figure into two areas The equal parts. Figure 1-1 The rectangles and circles in the analysis diagram are all center symmetrical figures, so as long as the symmetrical centers are respectively found,
