數(shù)學考題練習:下列語句中,正確的個數(shù)是①延長射線OA;②在線

更新時間:2024-01-12 12:57:43作者:貝語網校

下列語句中,正確的個數(shù)是

①延長射線OA;

②在線段AB的延長線上任取一點;

③延長線段BA到C,使BC=AB;

④田徑運動中200米賽跑,起點與終點的距離是200米;

⑤線段AB是點A和點B的距離

A.1個

B.2個

C.3個

D.4個

試題答案

A

下列語句中,正確的個數(shù)是②在線段AB的延長線上任取一點;其余的錯誤:①延長射線OA;(射線OA本身就向一方無限延伸,不需要延長)③延長線段AB到C,使BC=AB;④田徑運動中200米賽跑,起點與終點的距離是200米;(如果200米是彎道,那么起點與終點的距離小于200米)⑤線段AB的長度是點A和點B的距離
