正方形ABCD在坐標(biāo)系中的位置如圖所示,將正方形ABCD繞D點(diǎn)順時(shí)針旋轉(zhuǎn)90°后,B點(diǎn)的坐標(biāo)為

A.(4,0)

B.(4,1)

C.(-2,2)

D.(3,1)

試題答案

A

試題解析

根據(jù)旋轉(zhuǎn)的性質(zhì)作出旋轉(zhuǎn)后的圖形,寫出點(diǎn)B對(duì)應(yīng)點(diǎn)的坐標(biāo)即可得解.

解答:如圖,點(diǎn)B的對(duì)應(yīng)點(diǎn)B′的坐標(biāo)為(4,0).

故選A.

點(diǎn)評(píng):本題考查了坐標(biāo)與圖形變化-旋轉(zhuǎn),利用數(shù)形結(jié)合求解更加簡(jiǎn)便,準(zhǔn)確作出圖形是解題的關(guān)鍵.
