下面我们看两道竞赛题1.将一个正方形分割成n(n1)个小正方形,则n不可能取().(A)4(B)5(C)8(D)9(第十六届江苏省初中数学竞赛题)2.试设计一种方法,把一个正方形不重复不遗漏地分割成8个正方形(分得的正方形大小可以不相同);又问如何把正方形按上述要求分成31个正方形.(1997年安
Let’s look at two competition questions. 1. Split a square into n (n1) small squares, then n cannot be taken (). (A) 4 (B) 5 (C) 8 (D) 9 (16th Jiangsu Junior High School Mathematics Competition Question) 2. Try to design a method to divide a square into eight squares without any duplication. (The size of the divided squares may not be the same); ask how to divide the square into the above requirements. Squares. (1997
