Question

下面圖形中（　�。┎皇禽S對(duì)稱圖形．

A．長(zhǎng)方形

B．圓

C．等邊三角形

D．平行四邊形

Answer 1

分析：根據(jù)軸對(duì)稱圖形的特點(diǎn)和性質(zhì)，沿對(duì)稱軸把圖形對(duì)折兩邊的圖形完全重合，每組對(duì)應(yīng)點(diǎn)到對(duì)稱軸的距離相等；由此解答．

解答：解：長(zhǎng)方形是軸對(duì)稱圖形，它有1條對(duì)稱軸；圓是軸對(duì)稱圖形它有無數(shù)條對(duì)稱軸；等邊三角形是軸對(duì)稱圖形，它有3條對(duì)稱軸；平行四邊形不是軸對(duì)稱圖形；
故選：D．

點(diǎn)評(píng)：此題主要考查軸對(duì)稱圖形的特點(diǎn)和性質(zhì)，根據(jù)它特點(diǎn)和對(duì)稱軸的條數(shù)解決有關(guān)的問題．
