7、菱形具有而平行四邊形不具有的性質(zhì)是（　�。�

A、對(duì)角相等

B、對(duì)角線互相平分

C、對(duì)角線互相垂直

D、對(duì)邊相等

Answer 1

分析：菱形具有平行四邊形的全部性質(zhì)，比較菱形和平行四邊形的性質(zhì)即可解題．

解答：解：平行四邊形的對(duì)角相等，對(duì)角線互相平分，對(duì)邊平行且相等，故A、B、D選項(xiàng)錯(cuò)誤，
對(duì)角線互相垂直的平行四邊形為菱形，故C選項(xiàng)正確，
故選 C．

點(diǎn)評(píng)：本題考查了平行四邊形和菱形對(duì)角相等、對(duì)角線互相評(píng)分、對(duì)邊平行且相等的性質(zhì)，考查了菱形對(duì)角線互相垂直的性質(zhì)，本題中熟練掌握菱形和平行四邊形的性質(zhì)是解題的關(guān)鍵．
