如图,已知AB:AC=AE:AD.求证△ODB~△OEC

如图,已知AD/DB=AE/EC,求证 :AD/AB=AE/AC. 已知:如图,AC/AD=AB/DE=BC/AE.求证AB=AE 已知,如图,AD/AC=DE/AB=AE/BC,求证AB=AE 已知,如图,AD:AC=DE:AB=AE:BC 求证：AB=AE 已知：如图,AB=AC,AD=AE.求证：△ABE≌△ACD. 已知：如图,AB=AC,AD=AE.求证：△ABE≌△ACD. 已知：如图,AB=AC,AD=AE.求证：△ABE≌△ACD 已知:如图,AB=AC,AE=AD,求证:△ABD≌△ACE. 如图,已知AD.AB=AE.AC,求证△ABE~△ADC 如图,已知AB:AC=AE:AD.求证△ODB~△OEC 如图,已知：AB=AE,AC=AD,AC⊥AD,AB⊥AE.求证：ED⊥BC. 如图,已知AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证△EAC≌△DAB 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,已知△DAC≌△EAB.求证BE⊥CD 已知：如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证：△DAC≌△EAB.可能不太好看， 已知,如图,AB⊥AC,AB=AC,AD⊥AE,AD=AE.求证:△ABD≌△ACE 已知:如图,AD/AB=AE/BC求证：AD/AE=DB/EC和AB/DB=AC/EC 已知:如图,AD/AB=AE/BC求证：AD/AE=DB/EC和AB/DB=AC/EC 已知如图AB=AC,求证AB²=AD×AE
