剪拼图形问题,实际是几何学上的面积问题.但是,计算面积并不难,剪拼的技术可不简单!一般来说,解决这类剪拼图形问题没有法则可循,而要充分发挥一个人的直觉、机敏和创造力.本文从一道中考题入手,来谈谈如何将矩形剪拼成正方形的问题.例1(2011年天津中考题)如图1,有一张长为5、宽为3的矩形纸片ABCD,要通过适当的剪拼,得到一个与之面积相等的正方形. However, it is not difficult to calculate the area, and the technology of clipping is not easy! Generally speaking, there is no law to solve such a problem, but to give full play to one Human intuition, alertness and creativity.This article from a test questions to start, to talk about how to square rectangle cut into a square.Example 1 (2011 Tianjin exam questions) as shown in Figure 1, there is a length of 5, width 3 rectangular paper ABCD, through the appropriate cut spell, get an area equal to the square.
