折纸是一门艺术.一张小小的纸片可以折出栩栩如生的蝴蝶,可以折出惟妙惟肖的小人,也可以折出你百玩不厌的飞机……折纸不仅好玩,还可以帮助我们学习几何.一、折纸画几何图形如图1,在纸上画出线段AB,把纸张对折,使A点和B点重合,可以找到线段AB的中点C(折痕与AB的交点).通过折纸 Origami is an art. A small piece of paper can bring out lifelike butterflies. You can draw out lifelike villains, and you can also fold out your hundred planes. ... Origami is not only fun, but also helps us learn geometry. First, the origami geometry is shown in Figure 1. Draw a line segment AB on the paper and fold the paper in half, so that point A and point B coincide. You can find the middle point C of the line segment AB (the intersection of the crease and AB).
