我们已经学习了全等图形,以及怎样把 一个图形分成几个全等的图形.其实,图形的 分割还有许多种类,不一定就是分割成几个 全等图形,比如下面这道题: (1)将长10cm、宽9cm的长方形分割成 若干个边长为整数厘米的小正方形,怎样能 使分割成的小正方形数目尽量少? 像这类没有给出实际图形的题,如果图 不大,可以直接在纸上画出,如果图较大,无 We’ve learned about equal graphics, and how to divide a graphic into several equal graphics. In fact, there are many types of graphic segmentation, not necessarily split into several congruent graphics, such as the following: (1 ) How can a rectangle with a length of 10cm and a width of 9cm be divided into a number of small squares with integer sides in centimeters?
