给一张正方形的纸,如何通过折纸的方法,找到一边的任意等分点呢?本文给出一个简单的方法。如图一,设正方形ABCD的边长AD=1,当然,AD的中点对折一次便可折出,为了折出三等分点,将B点的一角折起,让B点落在AD上,使AB′=12,压平,设折痕为EF,此时,C点折到了C′点,而 To a square of paper, how to get through the origami method, to find an arbitrary point on the side? This article gives a simple method. As shown in Figure 1, suppose that the side length of the square ABCD is AD = 1, of course, the midpoint of the AD can be folded off once. In order to fold the third equal point, the corner of point B is folded up and the point B falls on the AD , So AB ’= 12, flatten, set the crease to EF, at this point, C point off to the C’ point
