如图,P是定长线段AB的三等分点,Q是直线AB上一点,且AQ-BQ=PQ,求PQ/AB的值
A_______P__________________B

如图,P是定长线段AB的三等分点,Q是直线AB上一点,且AQ-BQ=PQ,求PQ/AB的值 A_______P__________________B
当Q在AB之间时,PQ/AB的值为1/3
当Q在AB的延长线上时,PQ/AB的值为1
Q不可能在AB的反向延长线上

当Q在AB得延长线上时，不管P为那个三等分点答案都是1，当Q在线段AB上时，P为靠近A的三等分点时答案是1/3，当Q在线段AB上时，P为靠近B的三等分点时答案是1/9，

因为AQ-BQ=PQ唯一情况就是Q为线段AB的三等分点，AQ-BQ=PQ就如同2-1=1 PQ是一个三等分点就可以把它看成1，AB为三个三等分点就是3，所以的3/1........

A_______P________Q__________B---------Q'-------
解 （1） 因为AQ-BQ=PQ （2） 当点Q2在AB的延长线上时
所以AQ-BQ=AP=1/3AB=PQ 因为AQ'-AQ'=PQ'
所以PQ=1/3 所以AQ'-BQ'=3PQ=AB
所以PQ/AB=1
（算式里的Q'是设的第二个Q）
答;PQ/AB为1/3或者1。 （此题有两种答案）
