已知: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
点D、E在三角形ABC的边BC上,AB=AC,AD=AE,求证,BD=CE
已知:点D、E在三角形ABC的边BC上,AB=AC,AD=AE,求证:BD=CE
如图所示已知点D,E在△ABC的边BC上,AB=AC,AD=AE.求证BD=CE.(不能用证明三角形全等证明
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4,已知点D、E在△ABC的边BC上,AB=AC,AD=AE,求证:BD=CE
如图,已知点D,E在△ABC的边BC上,AB=AC,AD=AE.求证:BD=CE
已知:如图,点D,E在△ABC的边BC上,AB=AC,AD=AE.求证:BD=CE
AD等于AE ,点D,E在三角形abc的边bc上,BD等于CE,角ADE=角AED ,求证 :三角形ABD全等三角形AC
如图,点D、E三角形ABC的边BC上,AB=AC,BD=CE,求证:AD=AE.
