BE=DF,AE=CF,AE//CF,求证AD//BC全等三角形BE=DF,AE=CF,AE//CF,求证AD//BC。我发不了图片

BE=DF,AE=CF,AE//CF,求证AD//BC全等三角形BE=DF,AE=CF,AE//CF,求证AD//BC。我发不了图片 如图,已知BE=DF,AE=CF,AE∥CF,说明AB∥CD 已知BE=DF,AE=CF,AE‖CF,求证：AD‖BC 如图测,BE=DF,AE=CF,AE//CF,求证AD//BC 如图,已知BE=DF,AC=CF,AE‖CF.求证：AD‖BC. 如图,已知:BE=DF,AE=CF,AE平行CF.说明AB平行CD的理由 如图CD=AB,DF=BE,AE=CF,求证:DF//BE AE垂直BC,DF垂直BC,E,F是垂足,且AE=DF,AB=DC,求证CF=BE. 已知:如图,点A,B,C,D在一条直线上,AC=DB,AE=DF,BE=CF,求证:AE∥DF,BE∥CF 已知:如图,点A,B,C,D在一条直线上,AC=DB,AE=DF,BC=CF求证AE平行DF,BE平行CF 如图AB=CD,BE=CF,AE=DF求证OA=OD 如图,AB=CD,BE=DF,AE=CF,求证:EO=FO? 已知AB=CD,BE=DF,∠ABE=∠CDF,求证AE∥CF 已知AB=CD,BE=DF,AE=CF,问AB‖CD吗 如图,已知AD‖BC,AD=CB,AE=CF.求证:DF=BE AE=DF CE=BF AB=CD 问BE和CF平行吗?为什么? 如图,AE=DF,CE=BF,AB=CD,证明BE平行CF AD=CB,AD‖CB,BE=DF求证AE=CF
