Question

菱形和矩形一定都具有的性質(zhì)是（ ）
A．對(duì)角線相等
B．對(duì)角線互相平分
C．對(duì)角線互相垂直
D．每條對(duì)角線平分一組對(duì)角

Answer 1

【答案】分析：根據(jù)矩形的對(duì)角線的性質(zhì)（對(duì)角線互相平分且相等），菱形的對(duì)角線性質(zhì)（對(duì)角線互相垂直平分）可解．
解答：解：因?yàn)榫匦蔚膶?duì)角線互相平分且相等、菱形的對(duì)角線互相垂直平分，可知矩形、菱形都具有的特征是對(duì)角線互相平分．故選B．
點(diǎn)評(píng)：此題主要考查矩形、菱形的對(duì)角線的性質(zhì)．
