如图,已知AB=DC,AE=DF,CE=BF,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=BF,求证AF=DE
证明:
∵CE=BF,
∴BF+EF=EF+CE,
即BE=CF,
在△ABE与△DCF中,
┌ AB=DC,
┤ AE=DF,
└ BE=CF,
∴△ABE≌△DCF (SSS),
∴∠B=∠C,
在△ABF与△DCE中,
┌ AB=DC,
┤ ∠B=∠C,
└ BF=CE,
∴△ABF≌△DCE (SAS),
∴AF=DE.
如图,已知AB=DC,AE=DF,CE=BF,求证AF=DE
如图,在梯形ABCD中,AD//BC,AB=DC,AE//DC,DF//AB.试说明AE=DF.
已知:如图,AB=CD,AE=CF,BE=DF.求证:AF∥CE
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等于DC,AE等于DF,CE等于FB,求证AF等于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
如图,已知AB=DC,AC=DB,BE=CE,求证AE=DE
如图,已知AE垂直BC于E,DF垂直BC于F,AE=DF,AB=DC,求证AC垂直于BD
9.如图,在等腰梯形ABCD中,AD//BC,AE//DC,DF//AB.试说明AE=DF.
如图,已知AE/EB=DF/FC=/,求AB/EB,DC/FC,AB/AE,DC/DF的值
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.
如图,AB=CD,AE垂直BC,DF垂直BC垂足分别为E,F,CE=BF.求证AE=DF.
