如图所示,AB=AC,AD=AE,CD,BE相交于点O,求证：AO平分角DAE如图图不标准~

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 ab⊥ac.ad⊥ae .ab=ac .ad=ae .说明 be⊥cd 如图所示,ab=ac ad=ae,cd,be相交于点o,求证ao平分角dae 如图所示,AB=AC,AD=AE,CD,BE相交于点O,求证：AO平分角DAE如图图不标准~ 如图所示,AB=AC,AD=AE,CD、BE相交于点O.求证AO平分∠DAE 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 在△ABC中,AD⊥AB,AD=AB,AE⊥AC,AE=AC,求证：BE=CD 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AE⊥AD,AF⊥AB,AB//CD,AE=CD,AE=AD,AF=CD,求证AC=EF 如图所示,AD⊥AB,AE⊥AC,AD=AB,DC与BE相交于H,BE与AC相交于F,试说明CD=BE,CD⊥BE 如图,已知AB垂直AC,AD垂直AE,AB=AC,AD=AE,求证BE=CD且BE垂直CD. 如图,已知AB垂直AC,AD垂直AE,AB=AC,AD=AE,求证BE=CD且BE垂直CD.图在后面. 如图,已知AB垂直AC,AD垂直AE,AB=AC,AD=AE,求证BE=CD且BE垂直CD.图在后面. 已知,如图,AB⊥AC,AB=AC,AD⊥'AE,AD=AE,求证:(1)BE=CD;(2)BC⊥CD急!帮个忙呗! 如图所示,AD是△ABC的高,AE是△ABC的外接圆直径,求证:AB×AC= AE×AD.
