Question

11、矩形具有而菱形不具有的性質(zhì)是（　�。�

A、對(duì)角線互相平分

B、對(duì)角線互相垂直

C、對(duì)角線相等

D、對(duì)角線平分一組對(duì)角

Answer 1

分析：根據(jù)矩形的對(duì)角線互相平分、相等和菱形的對(duì)角線互相平分、垂直、對(duì)角線平分一組對(duì)角，即可退出答案．

解答：解：菱形的對(duì)角線互相平分、垂直、對(duì)角線平分一組對(duì)角，
矩形的對(duì)角線互相平分、相等，
∴矩形具有而菱形不具有的性質(zhì)是對(duì)角線相等，
故選C．

點(diǎn)評(píng)：本題主要考查對(duì)矩形的性質(zhì)，菱形的性質(zhì)等知識(shí)點(diǎn)的理解和掌握，能熟練地根據(jù)矩形和菱形的性質(zhì)進(jìn)行判斷是解此題的關(guān)鍵．
