将一个平面图形剪成若干块,然后拼成另一个与它等积的平面图形,这就是图形的剪与拼.这类题目形式多样、新颖有趣、是富有创意的动手操作性问题.它在中小学一些智力赛题以及中考题中也常出现.对于这类问题,切勿胡乱剪来,否则事倍功半,难以奏效.经验证明,只要充分应用科学的几何知识,仔细地计 Cut a flat figure into several pieces, and then spell into another with its flat plot, which is the shape of the cut and fight these kinds of topics in various forms, novel and interesting, is a creative hands-on problem. Primary and secondary intelligence questions as well as the middle school entrance examination questions are also often appear. For such issues, not indiscriminately cut, otherwise less effective, difficult to work. Experience has proved that as long as the full application of scientific knowledge of geometry, carefully
