几何课本中教了我们两种比较角的大小的方法,还有没有别的方法呢?请试试下面的方法. 角的大小是由它的两条边张开的程度而确定的,可利用这个规律在比较两个角(如图1中之∠AOB与∠COD)的大小时,分别
The geometry textbook teaches us two ways to compare the sizes of the corners. Is there any other way? Try the following method. The size of the corner is determined by the degree to which its two sides are open and can be used. This rule compares the two corners (such as ∠AOB and ∠COD in Figure 1)
