如图,AB=AE,AB⊥AE,AD=AC,AD⊥AC.点M是BC的中点,求证：DE=2AM亲们可以只写明做辅助线的的方法和较具体的思路就行咧的。

如图,AD⊥AE,AB垂直AC,AD=AE,AB=AC,AD⊥AE ,AB=AC,求证：三角形ABD≌三角形ACE 如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC? 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证BE⊥CD 如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证BE⊥CD 如图,已知：AB=AE,AC=AD,AC⊥AD,AB⊥AE.求证：ED⊥BC. 如图AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证:△DAC≌三角形EAB 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 如图ab:bd=ae:ce,求证ab:ac=ad:ae 如图,AB=AD,AC=AE, 如图,已知AD/DB=AE/EC,求证 :AD/AB=AE/AC. 如图AB=AE,AC=AD,ED=BC,AE⊥AB 求证BC⊥DE 如图,已知AE⊥AD,AF⊥AB,AB//CD,AE=CD,AE=AD,AF=CD,求证AC=EF 如图,AB‖CD,AD‖BC,AE⊥AB,AF⊥AD,AE=AB,AF=AD,试说明AC=EF 如图,已知AD//BC,AD=BC,AE⊥AD,AF⊥AB,AE=AD,AB=AF.求证：AC=EF. 如图,AD∥BC,AD=BC,AE⊥AD,AF⊥AB,且AE=AD,AF=AB,求证：AC=EF. ab⊥ac.ad⊥ae .ab=ac .ad=ae .说明 be⊥cd
