正五角星折剪的方法
1．首先准备折剪工具：正方形纸一张、剪刀、铅笔、直尺；
2．如图1所示，按图1把正方形纸对折；

3．将图1对折，折成两个小正方形，并折出其中1个正方形的对角线，并按图2所示用铅笔“打”两条辅助线，获得“中心点”（如图2所示）；

4．把对折后的“左下角”与这个中心点重合（如下图3）

5．再反过来对折（如图4所示）

6．“右下角”的边也对折到“中缝”（如图5所示）

图5
6．按照图示反过来对折（如图6所示）

7．最后折成这个形状（如图7所示）

图7
8．用剪刀按如图8所示的斜线（不垂直两条边中的任何一条），把多余的纸剪去（如图8所示）
![](https://wkrtcs.bdimg.com/rtcs/image?w=346&md5sum=1d65722eb3c0f454701761b228272c9c&sign=3408e19e61&rtcs_flag=1&rtcs_ver=3.1&l=webapp&bucketNum=46&ipr={"t":"img","w":"346","h":"238","dataType":"png","c":"word/media/image8.png","imgOriW":346,"imgOriH":238})

9．展开后就获得了正五角星（如图9所示）
