如圖是一個五環(huán)圖案,它由五個圓組成,下排的兩個圓的位置關(guān)系是

A.內(nèi)含

B.外切

C.相交

D.外離

試題答案

D

試題解析

根據(jù)兩圓交點(diǎn)的個數(shù)來確定圓與圓的位置關(guān)系.

解答:∵下排兩圓沒有交點(diǎn),∴

它們的位置關(guān)系是外離.

故選D.

點(diǎn)評:本題主要考查了圓與圓之間的位置關(guān)系,要掌握住特點(diǎn)依據(jù)圖形直觀的判斷.

兩圓之間有5種位置關(guān)系:無公共點(diǎn)的,一圓在另一圓之外叫外離,在之內(nèi)叫內(nèi)含;有唯一公共點(diǎn)的,一圓在另一圓之外叫外切,在之內(nèi)叫內(nèi)切;有兩個公共點(diǎn)的叫相交.
