AB⊥AC,AD⊥AE,AB=AD,BC=DE,求证AM=AN图片图片

如图,已知：AB=AE,AC=AD,AC⊥AD,AB⊥AE.求证：ED⊥BC. 如图,已知AD//BC,AD=BC,AE⊥AD,AF⊥AB,AE=AD,AB=AF.求证：AC=EF. 如图,AD∥BC,AD=BC,AE⊥AD,AF⊥AB,且AE=AD,AF=AB,求证：AC=EF. ab⊥ac.ad⊥ae .ab=ac .ad=ae .说明 be⊥cd 如图,AB‖CD,AD‖BC,AE⊥AB,AF⊥AD,AE=AB,AF=AD,试说明AC=EF 如图,已知AE⊥AD,AF⊥AB,AF=AB,AE=AD=BC,AD‖BC,求证AC⊥EF 梯形ABCD中,AD//BC,AB=CD,AE⊥BC于点E,AE=4AD,AC=BC,求AD/BC的值 如图,DE//BC,请问AD:AC=AE:AB?AD:AE=AB:AC? AD=AC AD⊥BC AD=AE AB平分∠DAE,请写出图中三处的全等三角形 如图AB=AE,AC=AD,ED=BC,AE⊥AB 求证BC⊥DE 已知AE⊥AD,AF⊥AB,AE=AD=BC,AD‖BC,求证:⑴AC=EF⑵AC⊥EF如题 AB⊥AC,AD⊥AE,AB=AD,BC=DE,求证AM=AN图片图片 AE是圆O的直径,AD⊥BC,求证:AD·AE=AB·AC这是图片 如图9,AD//BC,AE⊥AD且AE=AD,AF⊥AB且AF=AB.则AC与EF是否相等?为什么? AB=AC AD⊥BC AE=EC AD=18 BE=15则BC= 已知,如图,AB⊥AC,AB=AC,AD⊥'AE,AD=AE,求证:(1)BE=CD;(2)BC⊥CD急!帮个忙呗! 如图,AB=AE,AB⊥AE,AD=AC,AD⊥AC,M为BC中点,求证:DE=2AM 如图,在△ABC中,AD⊥AB,AD=AB,AE⊥AC,AE=AC,M为BC中点 求证：2AM=DE
