作业帮AB=DC,DF=BE,AF=CE,求证：（1）△ABE≌CDF；（2）DC∥AB.
AB=DC,DF=BE,AF=CE,求证：（1）△ABE≌CDF；（2）DC∥AB.
如图,AB=DC,DF=BE,AF=CE,试证明∠ABE=∠CDF.
如图所示:BA⊥AC,DC⊥AC,AF=CE,BE=DF.求证;△ABE全等于△CDF,BE∥DF
如图,已知AB//CD,BE//DF,AF=CE,说明:(1)△ABE≌△CDF(2)∠EBF=∠FDE
如图,已知AB=DC AE=DF .CE=BF 求证:AF=DE
已知如图AB=DC,AE=DF,CE=FB求证AF=DE
如图,已知AB=DC,AE=DF,CE=FB,求证AF=DE
AB=DC.AE=DF.CE=BF.求证：AF=DE.
AB=DC,AE=DF,CE=FB,求证AF=DE
如图,已知AB=DC,AE=DF,CE=BF,求证：AF=DE
已知:如图,AB=DC,AE=DF,CE=FB,求证:AF=DE
AB‖DC,BC‖DF,CE垂直平分AF,求证AD=BC
