已知:如图6-7,AD=AE,AB=AC,∠DAE=∠BAC.求证:BD=CE.
已知:如图,AB=AC,AD=AE,BD=CE,求证:∠BAC=∠DAE
已知:如图,AD=AE,AB=AC,∠DAE=∠BAC.求证:BD=CE.
已知,如图,AB=AC,AD=AE,BD=CE,AC平分DE.求证:(1)∠BAC=∠DAE;(2)∠BAD=∠CAD.
如图,已知AB=AC,AD=AE,BD=CE.试说明:∠BAC=∠DAE
如图,已知∠BAC=∠DAE,∠1=∠2,BD=CE.求证:AB=AC,AD=AE
(1)如图,已知∠BAC=∠DAE,AB=AC,AD=AE,求证:∠B=∠C,BD=CE
如图,已知∠BAC=∠DAE ,∠ABD=∠ACE ,BD=CE 求证:AB=AC,AD=AE
已知:如图所示,AB=AC,BD=CE,AD=AE,求证∠BAC=∠DAE
如图,AB=AC,AD=AE,BD=CE,求证角BAC=角DAE
如图,AB=AC,AD=AE,BD=CE.求证角bac=角dae
如图 已知角bac=角dae 角1=角2 bd=ce 求证ab=ac ad=ae
