如图△ABC,△DEF均为锐角三角形,AB=DE,AC=DF,∠B=∠E,求证△ABC≌△DEF(快一点啊!马上要!
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.
已知,如图所示.E、C两点在线段BF上,AB平行DE,AC平行DF,BE=CF,求证:△ABC全等于△DEF
如图,AB∥DE,AC∥DF,BE=CF.求证:△ABC≌△DEF.
已知,如图BE=CF,AB=DE,AC=DF,求证△ABC≌△DEF
如图,已知∠B=∠E=90°,AC=DF,BF=EC.求证:△ABC≌△DEF.
如图所示,A,E,B,D在同一直线上,在△ABC于△DEF中,AB=DE,AC=DE,AC∥DF.
如图,A,E,B,D在同一直线上,在△ABC和△DEF中,AB=DE,AC=DF,AC∥DF.
已知,如图,∠B=∠DEF,AB=DE,△ABC≡△DEF
如图,已知AB=DE,AC=DF,CE=BF,求证△ABC全等于△DEF
