試題解析

的都可以,所以4,9都可以.設(shè)想一個(gè)邊長(zhǎng)為8的正方形先切成4個(gè)邊長(zhǎng)4的小正方形,把每個(gè)邊長(zhǎng)為4的小正方形沿兩條對(duì)角線切開(kāi),可以切出4個(gè)直角邊是2 的等腰直角三角形,每?jī)蓚€(gè)直角邊是2 的等腰直角三角形都能組成1個(gè)2 為邊長(zhǎng)的正方形于是邊長(zhǎng)為8的,可以分割為8個(gè)邊長(zhǎng)為2 的正方形,于是邊長(zhǎng)為8的也可以,答案就有了.

解答:都可以,所以4,9都可以,

邊長(zhǎng)為8的,可以分割為8個(gè)邊長(zhǎng)為2 的正方形.

故選B.

點(diǎn)評(píng):本題考查正方形的性質(zhì),正方形的四個(gè)邊相等.
