点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:
点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC
点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC
点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC
因为:D、E在BC上 AD=AE 所以:∠ADE=∠AED ∠ADB=∠AEC 又因:BD=CE AD=AE 所以:△ADB≌△AEC 所以:AB=AC
点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC
点D,E在△ABC边BC的上 AB=AC,AD=AE .证明BD=CE
点D、E在三角形ABC的边BC上,AB=AC,AD=AE,求证,BD=CE
在△ABC的边BC上有点D,点E,且AD=AE,BD=CE,说明△ABC是等腰三角形
如图,在△ABC的边BC上有点D,点E,且AD=AE,BD=CE,说明△ABC是等腰三角形
如图,点D.E在△ABC的边BC上,AD=AE,BD=CE.试说明三角形ABC是等腰三角形
如图,在△ABC中,点D,E在边BC上,AD=AE.那么BD=CE吗?请说明你的理由.
如图,点D,E在△ABC的边BC上,BD=CE,AD=AE,求证:AB=AC(不要用全等的解法)
点D、E在△ABC的边BC上,AB=AC,AD=AE,BD=CE 求证 △ABF≌△ACD图片= =
如图所示,点D.E在△ABC的边BC上,AB=AC,AD=AE,BD=CE.求证:△ABE≌△ACD
解一道初一数学题如图,点D、E在△ABC的边BC上.AD=AE,BD=EC,试说明:AB=AC
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC
如图4,已知点D、E在△ABC的边BC上,AB=AC,AD=AE,求证:BD=CE
如图,点D,E在△ABC的边BC上,AB=AC,BD=CE,求证:AD=AE.
已知:如图,点D、E在△ABC的边BC上,AD=AE,∠BAD=∠CAE.求证:AB=AC
已知点D、E在△ABC的边BC上,AD=AE,BD=EC.求证:AB=AC.
点D,E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC方法最好不是全等
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】
