如图所示,AB=AC,AD=AE,∠1=∠2.求证:△ABC≌△ACERT
如图所示,AB=AC,AD=AE,∠1=∠2.求证:△ABC≌△ACE
RT
如图所示,AB=AC,AD=AE,∠1=∠2.求证:△ABC≌△ACERT
证明:∵∠1=∠2
∴∠CAE=∠1+∠BAE=∠2+∠BAE=∠BAD
∵AB=AC,AD=AE
∴△ABD≌△ACE
如图所示,AB=AC,AD=AE,DC=EB,求证∠1=∠2?
如图所示,已知AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证:BE=DC
如图所示,已知AB⊥AC,AD⊥AE,AB=AC,AD=AE,求证:BE=DC非常急
如图所示,AD=AE,角1=角2,BD=CE,求证:AB=AC
如图所示,AB=AC,AD=AE,∠1=∠2.求证:△ABC≌△ACERT
如图所示,AB乘AE=AD乘AC,且∠1=∠2求证△ABC∽△ADE
如图所示,AD是△ABC的高,AE是△ABC的外接圆直径,求证:AB×AC= AE×AD.
如图所示,AB=AC,BD=CE,AD=AE,求证:角ADE=角AED
如图所示,已知AB=AC,AD=AE,请说明BD=CE
如图所示,AD⊥AB,AE⊥AC,且AD=AB,AE=AC.试说明:BE=CD,BE⊥CD
如图所示,AD⊥AB,AE⊥AC,且AD=AB,AE=AC.试说明:BE=CD,BE⊥CD
已知:如图所示,AB=AC,BD=CE,AD=AE,求证∠BAC=∠DAE
如图所示,AB=AE,AC=AD,∠BAD=∠EAC,试说明ED=BC图
如图所示,AB=AC,AD=AE,CD、BE相交于点O.求证AO平分∠DAE
ab⊥ac.ad⊥ae .ab=ac .ad=ae .说明 be⊥cd
如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC?
如图所示,在△ABC和△ADE众,AB=AC,AD=AE,∠DAB=∠EAC,AD,AE交BC于点F,G.求证DE‖B如图所示,在△ABC和△ADE中,AB=AC,AD=AE,∠DAB=∠EAC,AD,AE交BC于点F,G.求证DE‖BC
已知如图所示,AB=AD,BC=DE,∠1=∠2,求证:(1)AC=AE,(2)∠CAE=∠CDE
