Question

11、經(jīng)過(guò)平移，對(duì)應(yīng)點(diǎn)所連的線段平行且相等，對(duì)應(yīng)線段（　�。�

A、平行且垂直

B、平行且相等

C、平行或垂直

D、不平行，也不相等

Answer 1

分析：根據(jù)平移的性質(zhì)，圖形經(jīng)過(guò)平移，對(duì)應(yīng)點(diǎn)所連的線段平行且相等，對(duì)應(yīng)線段平行且相等，可直接求得答案．

解答：解：根據(jù)圖形經(jīng)過(guò)平移，對(duì)應(yīng)點(diǎn)所連的線段平行且相等，對(duì)應(yīng)線段平行且相等．
故選B．

點(diǎn)評(píng)：本題考查平移的基本性質(zhì)是：①平移不改變圖形的形狀和大小；②經(jīng)過(guò)平移，對(duì)應(yīng)點(diǎn)所連的線段平行且相等，對(duì)應(yīng)線段平行且相等，對(duì)應(yīng)角相等．
