已知:如图AB=AD,AC=AE,∠BAD=∠CAE ,求证:OA平分∠BOE
如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE
已知:如图,AB=AD,AC=AE,∠BAD=∠CAE,求证:BC=DE
已知:如图,AB=AD,AC=AE,∠CAE=∠BAD.求证△EAD≌△CAB
已知:如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE
如图,AB平行AC,∠BAD=∠CAE,AD=AE,求证:△ABE≌△ACD.(SAS)
如图,AB平行AC,∠BAD=∠CAE,AD=AE,求证:△ABE≌△ACD.
如图,已知AB=AC,AD=AE,DE=BC,且∠BAD=∠CAE.求证:四边形BCED是矩形
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC【用三线合一】
如图,已知AB分之AE = BC分之ED = AC分之AD 证明∠BAD=∠CAE
AB=AD,AC=AE,BC=DE.求证∠BAD=∠CAE
如图,已知AC平分∠BAD,∠1=∠2.求证AB=AD
