如图,AC=DF,AC∥DF,AE=DB,求证：①△ABC≌△DEF.②BC=EF.

如图,AC=DF,AC∥DF,AE=DB,求证：①△ABC≌△DEF.②BC=EF. 如图,AB=DE,AC//DF,BC//EF,求证:△ABC≌△DEF 1.如图,AB=DE,AC//DF,BC//EF,求证：△ABC≌△DEF. 如图,BC‖EF,AC‖DF,AE=DB,求证;BC=EF 如图,AB=DE,AC∥DF,BC∥EF,求证△ABC全等于△DEF 如图 AB//DE,AC//DF,BC//EF,求证△ABC全等于△DEF 已知如图,AD=BE,AC=DF,BC=EF,证：△ABC≌△DEF. 已知:如图,AC=DF,∠A=∠D,AE=DB.求证:BC=EF. 如图,ac=df,角a=角d,ae=db求证bc=ef 如图,△ABC的AB边和△DEF的EF边都在直线MN上,AC=DF,AE=BF,BC=DE. 如图,已知AB⊥BC,AE⊥EF,AC=DF,BE=CF.求证AC平行于DF. 如图,已知AD=BE,AC=DF,BC=EF.求证:△ACB≌△DFE;求证：AC∥DF
