Question

7、在下列性質(zhì)中：①對(duì)角線(xiàn)互相平分；②對(duì)邊相等；③對(duì)角線(xiàn)互相垂直且相等；④對(duì)角相等．矩形和菱形都具有的性質(zhì)是（　�。�

A、①②③

B、①②④

C、①③

D、③④

Answer 1

分析：矩形和菱形都具有的性質(zhì)是：對(duì)角線(xiàn)互相平分；對(duì)邊相等；對(duì)角相等．

解答：解：矩形的性質(zhì)對(duì)角線(xiàn)互相平分；對(duì)邊相等；對(duì)角相等；對(duì)角線(xiàn)相等
菱形的性質(zhì)是對(duì)角線(xiàn)互相平分；對(duì)邊相等；對(duì)角線(xiàn)互相垂直；對(duì)角相等．故選B．

點(diǎn)評(píng)：熟練掌握矩形和菱形的性質(zhì)是解決本題的關(guān)鍵．
