画线段AB=6cm,在AB上取一点P,使AP=BP,在AB的延长线上取一点C,使AC=3BC,在线段BA延长线上取一点D

画线段AB=6cm,在AB上取一点P,使AP=BP,在AB的延长线上取一点C,使AC=3BC,在线段BA延长线上取一点D 画线段AB=6cm,在AB上取一点P,使AP=BP,在AB的延长线上取一点C,使AC=3BC,在线段BA延长线 画线段AB,在AB的延长线上取一点C,使BC=2AB,再在BA的延长线上取一点D. 画线段AB=3cm,在线段上取一点K,使AK=BK,在线段AB的延长线上取一点C,使AC=3BC,在线段BA的延长线上取 画线段AB=3cm,在线段上取一点M,使AM=BM,在线段AB的延长线上取一点C,使AC=3BC,在线段BA的延长线上取 画线段AB,在AB的延长线上取一点C,使BC=2AB,再在BA的延长线上取一点D,使DA=AB,取AB中点E,若DE=6 画线段AB,在AB的延长线上取一点C,使BC＝2AB,再在BA的延长线上取一点D,使DA＝AB,取AB中点E,若DE=6 画线段AB,在AB的延长线上取一点C使BC=2AB,再在BA的延长线上取一点D,使DA=AB;再在AB中取一点E,且DE 画线段AB,在AB的延长线上取一点C,使BC=2AB. 在线段AB的延长线上取一点C,使BC=2AB,再在BA的延长线上取一点D.使DA=3AB,则线段AC是线段BD的几分之几 画线段AB,在AB的延长线上取一点C,BC=二分之一AB,再在BA的延长线上取一点D,使DA=2AB,取AB的中点,若D 已知线段AB,在BA的延长线上取一点C,使CA=3AB,再在线段AB的延长线上取一点D,使BD=2AB,求线段CD:AC
