如图,点D.E在三角形ADC的边BC上,AD=AE,BD=EC,说明:AB=AC的理由
如图,点D,E在三角形ABC的边BC上.若AD=AE,BD=CE,则AB=AC.请说明理由.
如图,点D,E在△ABC的边BC上,若AD=AE,BD=CE.则AB=AC,请说明理由.
如图,点D.E在三角形ABC的边BC上,AB=AC,AD=AE,试说明BD=CE
如图,已知在△ABC中,点D、E在BC上,AB=AC,AD=AE,请说明BD=CE的理由
点D.E在△ABC的边BC上,AD=AE,BD=EC,求证:AB=AC
三角形abc,d,e为bc上的点,且bd=ec,求证ab+ac大于ad+ae
如图,点D,E在三角形ABC的边BC上,AB=AC,AD=AE.求证BD=CE
如图,点D,E在三角形ABC的边BC上,AB=AC,AD=AE.求证BD=CE.
如图,已知:点D,E在边BC上,AD=AE,∠ADE=∠AED,BD=EC,那么AB=AC是否成立?
点D E在三角形ABC的边BC上 AB=AC AD=AE 求证BD=CE
点D,E在三角形ABC的边BC上,AB=AC,AD=AE,求证BD=CE
点D、E在三角形ABC的边BC上,AB=AC,AD=AE,求证,BD=CE
