如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证:(1)△DAC≌△EAB;(2)BE⊥CD.

如图,AB⊥AC,AD⊥AE,AB=AC,AD=AE.求证BE⊥CD 已知如图,AB=AC,∠1=∠2,AD⊥CD,AE⊥BE,求证:AD=AE 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 ab⊥ac.ad⊥ae .ab=ac .ad=ae .说明 be⊥cd   如图,已知AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗?为什么?  如图,已知AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗?为什么? 如图,已知AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗,为什么 如图,在△ABC中,AB=AC,AD⊥BD,AE⊥CE,且AD=AE,BD和CE交于点O.说明∠EAB=∠DAC AB=AC,AE=AD,∠EAB=∠DAC,那么BE与CD相等吗?为什么? 如图,已知AE⊥AD,AF⊥AB,AB//CD,AE=CD,AE=AD,AF=CD,求证AC=EF 已知,如图,AB⊥AC,AB=AC,AD⊥AE,AD=AE.求证:△ABD≌△ACE 如图,已知AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证△EAC≌△DAB
