已知,如图AB=AC,AD=AE,∠BAC=∠DAE
已知,如图AB=AC,AD=AE,∠BAC=∠DAE
如图,AB=AC,AD=AE,∠BAC=∠DAE=90°
已知:如图∠DAE=∠BAC,AB=AC,∠B=∠C求证:AD=AE
已知:如图,AB=AC,AD=AE,BD=CE,求证:∠BAC=∠DAE
如图,已知AB=AC,AD=AE,BD=CE.试说明:∠BAC=∠DAE
已知:如图,AD=AE,AB=AC,∠DAE=∠BAC.求证:BD=CE.
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,AC平分DE.求证:(1)∠BAC=∠DAE;(2)∠BAD=∠CAD.
如图,AB=AC,AD=AE,∠BAC=∠DAE=α,求∠AOE.
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,AB=AC,AD=AE,你能说明BD=CE,∠ABD=∠ACE么?T0T)
