已知:如图,AB=AE,AC=AD,BC=DE,C、D在边BE上.求证:∠CAE=∠DAB
如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC【用三线合一】
已知:如图,AB=AD,AC=AE,∠BAD=∠CAE,求证:BC=DE
已知:如图,AB/AD=BC/DE=AC/AE,求证:∠BAD=∠CAE
1.如图,∠DAB=∠CAE,AB=AE,求证:BC=DE.
已知:如图,点D,E在三角形ABC的边BC上,AD=AE,角BAD=角CAE 求证:AB=AC 要
如图,已知AB=AC,AD=AE,DE=BC,且∠BAD=∠CAE.求证:四边形BCED是矩形
AB=AD,AC=AE,BC=DE.求证∠BAD=∠CAE
已知,在△ABE中,C、D分别为AB、BE上的点,且AD=AE,△BCD为等边三角形.求证BC+DE=AC
数学题求解,已知,如图,点d,e分别是在ab ,ac上,ad÷ab=ae÷ac求证de平行bc
如图,已知在△ABC中,D,E在BC上,且AD=AE,AB=AC,BE=CD.试说明∠BAD=∠CAE
