已知,如图:已知线段AB,点C在AB的延长线上,AC=2BC,D在AB反向延长线上,BD=3/5DC.急!
已知线段ab,在ab的延长线上取一点c点c,使ac=2bc,在ab的反向延长线上取一点d,使da=2ab,那么线段AC是
1、已知线段AB=5,延长AB到点C,使AC=7cm,在AB的反向延长线上取点D,使BD=4BC设线段CD的中点为E,问
如图,已知线段AB=6cm,点C在线段AB的延长线上,点D在AB的反向延长线上,且CB=1/3AB,AD=1/2AB,求
已知线段AB,在AB的延长线上取一点C,使AC=2BC,在AB的反向延长线上取一点D,使DA=2AB,那么线段AC是线段
已知线段AB,在AB的延长线上取一点C,使AC=2BC,在AB的反向延长线上取一点D,使AD=2AB,则线段CD是线段B
已知AB,在AB的延长线上取一点C,使AC=2BC,在AB的反向延长线上取一点D,使DA=2AB,那么线段AC是线段DB
已知线段AB=5cm,点C在线段AB的延长线上,点D在线段AB的反向延长线上,且B为线段AC中点,AD为BC的2倍,求C
已知线段ab,在ab的延长线上取一点c,使bc=ab,再在ab的反向延长线上取一点d,使da=2ab,线段db等于线段b
线段AB的延长线上取点C,使BC=2AB,在BA的延长线上取点D,使DA=AC,1线段DC=线段AB几倍2线段BC=线段
已知线段AB,在AB的延长线上取一点C,使BC=2AB在AB的反向延长线上取一点D,使DA=2AB,使DA=2AB,那么
已知线段AB,在AB的延长线上取一点C,使BC=2AB,再在AB的反向延长线上取一点D,使DA=2AB,
已知线段AB,在AB的延长线上取一点C,使BC=AB,在BA的延长线上取一点D,使DA=2AB.
