有些國家的國旗設(shè)計(jì)成了軸對(duì)稱圖形,觀察下列代表國旗的圖案中,你認(rèn)為是軸對(duì)稱圖形的是

A.

B.

C.

D.

試題答案

A

試題解析

根據(jù)軸對(duì)稱圖形的概念求解.如果一個(gè)圖形沿著一條直線對(duì)折后兩部分完全重合,這樣的圖形叫做軸對(duì)稱圖形.這條直線叫做對(duì)稱軸.

解答:根據(jù)軸對(duì)稱的概念可知:A是軸對(duì)稱圖形,符合題意;

B、C、D都不是軸對(duì)稱圖形,不符合題意.

故選A.

點(diǎn)評(píng):掌握軸對(duì)稱圖形的概念.軸對(duì)稱圖形的關(guān)鍵是尋找對(duì)稱軸,圖形兩部分折疊后可重合.
