如图,△ABC中,AB=AC,AD是高,求证:∠BAD=∠CAD.
如图,△ABC中,AB=AC,AD是高,求证:∠BAD=∠CAD.
如图△ABC中,AB=AC,AD是高.求证:(1)BD=CD;(2))∠BAD=∠CAD 最好用HL证明的
如图,△ABC中,AB=AC,AD是高.求证:(1)BD=CD(2)∠BAD=∠CAD
如图,在三角形ABC中,AB=AC,AD是高.求证:(1)BD=CD (2)∠BAD=∠CAD
已知:如图,△ABC是等腰三角形,AB=AC,AD是高,求证:BD=DC;∠BAD=∠CAD
如图,在三角形ABC中,AB=AC,AD是高,求证1:AB=DC 2:角BAD=角CAD 要过
2第7题△ABC中,AB=AC,AD是高。求证(1)BD=CD(2)∠BAD=∠CAD
如图在角ABC中,AB=AC.AD是高求证1.BD=CD 2.角BAD=角cad
如图,在三角形ABC中,∠BAD=∠CAD,AD=DB,DC垂直AC,求证AB =2AC
如图,在三角形abc中,ab等于ac,ad是高求证(1)bd等于cd(2)角bad等于角cad
如图,在三角形abc中,ab等于ac,ad是高求证(1)bd等于cd(2)角bad等于角cad
如图,在三角形ABC中,AB等于AC,AD是高,求证:BD等于CD;(2)角BAD等于角CAD.
