已知:如图所示,AB=AC,BD=CE,AD=AE,求证∠BAC=∠DAE
如图所示,已知∠BAC=∠DAE,∠ABD=∠ACE,BD=CE.求证:AB=AC,AD=AE
如图所示,已知∠BAC=∠DAE,∠ABD=∠ACE,BD=CE.求证:AB=AC,AD=AE急急急!!!!!!!
已知AB=AC,AD=AE,∠BAC=∠DAE.求证:BD=CE.
如图,已知AB=AC,∠ABD=∠ACE,∠BAC=∠DAE求证:BD=CE...
已知:如图∠DAE=∠BAC,AB=AC,∠B=∠C求证:AD=AE
如图,已知AB=AC,AD=AE,BD=CE.试说明:∠BAC=∠DAE
已知:如图,AB=AC,AD=AE,BD=CE,求证:∠BAC=∠DAE
已知,如图6-7,AD=AE,AB=AC,∠DAE=∠BAC求证:BD=CE
如图,已知AB=AC,AD=AE,∠BAC=∠DAE求证BD=CE
如图所示:三角形ABC的两边AB、AC的垂直平分线分别交BC于D、E两点,且∠BAC+∠DAE=150°,求∠的度数.求∠BAC的度数
如图,已知∠BAC=∠DAE ,∠ABD=∠ACE ,BD=CE 求证:AB=AC,AD=AE
如图,已知∠BAC=∠DAE,∠1=∠2,BD=CE.求证:AB=AC,AD=AE
如图,已知∠BAC=∠DAE,∠1=∠2,BD=CE.求证:AB=AC,AD=AE
已知∠BAC=∠DAE,∠ABD=∠ACE,BD=CE,说明AB=AC,AD=AE,
如图,已知∠BAC=∠DAE,AB=AC,AD=AE,你能说明BD=CE,∠ABD=∠ACE么?T0T)
已知,如图AB=AC,AD=AE,∠BAC=∠DAE求证:(1)△ABD≌△ACE (2)∠ADB=∠AEC
如图,已知∠BAC=∠DAE,∠ABD=∠ACE,BD=CE,那么AB与AC,AD与AE有什么数量关系?
