如图所示,在△ABC中AB=AC,BD⊥AC于D,CE⊥AB于E,BD,CE交于F,说明AF平分∠BAC
在三角形ABC,AB=AC,BD垂直于AC于D,CE垂直于AB于E,BD,CE相交于F.求证AF平分角BAC
如图,在三角形ABC中,AB=AC,BD⊥AC于点D,CE⊥AB于点E,CE相交于点F,求证AF平分∠BAC
如图所示,在△ABC中,AB=AC,∠A=90°,BD平分∠ABC交AC于D,CE⊥BD交BD的延长线于点E,则CE=_
(1)已知:如图,在△ABC中,∠BAC=90°,AB=AC,直线AF交BC于F,BD⊥AF于D,CE⊥AF于E.求证:
如图,在Rt△ABC中,AB=AC,∠BAC=90°,BD平分∠ABC交AC于点D,CE⊥BD交BD的延长线于点E.
如图:在三角形ABC中,AB=AC,BD垂直AC于D,CE垂直AB于E,BD、CE相交于F,求证:AF平分角BAC
已知:如图,在△ABC中,AB=AC,AD平分∠BAC,CE⊥AB于E,交AD于F,AF=2CD
1.如图,在Rt△ABC中,∠BAC=90°AB=AC,BD平分∠ABC,与AC交于点D,CE⊥BD交BD的延长线与点E
Rt△ABC中,∠BAC=90°,AB=AC,BD平分∠ABC交与AC于D,作CE⊥BD交BD的延长线于E,交BA的延延
如图,在△ABC中,AC⊥BC,CE⊥AB于E,AF平分∠CAB交CE于点F,过点F作FD∥BC交AB于点D,说明AC=
如图,Rt△ABC中,∠BAC=90°,AB=AC,BD平分∠ABC交AC于D,作CE⊥BD交BD的延长线于E,过A作A
已知:如图在△ABC中,∠BAC=90°,AB=AC,BD平分∠ABC,CE⊥BD交BD的延长线于E.求证BD=2CE.
