已知如图AB=DC,AE=DF,CE=FB求证AF=DE
已知如图AB=DC,AE=DF,CE=FB求证AF=DE
已知如图AB=DC,AE=DF,CE=FB求证AF=DE
CE=FB
CE+EF=FB+EF
即CF=BE
又因为AB=DC ,AE=DF
三角形AEB全等三角形DFC
所以角AEB=角DFC
又因为,AE=DF,EF=EF(公共边)
所以三角形AEF全等三角形DFE
所以AF=DE
已知:如图,AB=DC,AE=DF,CE=FB,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=BF 求证:AF=DE
如图,已知AB=DC,AE=DF,CE=FB,求证AF=DE
如图,已知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,AD=CD CE=BF DF=AE 求证AB‖DC
已知:如图,E﹑F是线段BC上的两点,AB∥CD,AB=DC,CE=BF.求证:AE=DF.
已知:如图,E﹑F是线段BC上的两点,AB∥CD,AB=DC,CE=BF.求证:AE=DF.
已知如图,点E,F在BC上BF=CE,AB=DC,AE=DF求证∠A=∠D
如图,已知AE/EB=DF/FC=/,求AB/EB,DC/FC,AB/AE,DC/DF的值
如图,已知AE⊥BC,DF⊥BC,E、F是垂足,AE=DF,AB=DC,求证AC=DB.没人回答...就...
如下图,AB=DC,BF=CE,AE=DF,求证AB//CD
如图,已知,AB=CD,AE⊥BC于E点,DF⊥BC于F,AE=DF,求证CE=BF
如图,已知AB=CD,AE=BF,CE=DF,求证:∠E=∠F
如图,已知,AB=CD,CE=DF,AE=BF,则CE‖DF吗?为什么?
如图,AB//DC,AB=DC,点E、F在BD上,BE=DF.求证:AE//CF
如图所示,已知AB=DC,AE=DF,CE=BF试说明AF=DE
