如圖,Rt△ABC沿直角邊BC所在直線向右平移到Rt△DEF,則下列結論中,錯誤的是

A.BE=EC

B.BC=EF

C.AC=DF

D.△ABC≌△DEF

試題答案

A

試題解析

把一個圖形整體沿某一直線方向移動,會得到一個新的圖形,新圖形與原圖形的形狀和大小完全相同.所以Rt△ABC與Rt△DEF的形狀和大小完全相同,即Rt△ABC≌Rt△DEF.

解答:∵RRt△ABC沿直角邊BC所在直線向右平移到Rt△DEF

∴Rt△ABC≌Rt△DEF

∴BC=EF,AC=DF

所以只有選項A是錯誤的,故選A.

點評:本題涉及的是全等三角形的知識;解答本題的關鍵是應用平移的基本性質.
