As shown in the figure, in rectangular ABCD, it is known that ab = 3aD, e and F are two bisectors of AB, AC and DF intersect at point G, and an appropriate rectangular coordinate system is established

(1) According to the meaning of the title, △ Abe GBE, e is the mid point of ad -- "eg = the mid point of ad --" eg = the middle point of ad -- "-" eg = the middle point of ad -- "-" eg = the ad -- "eg = ad --" - (eg = eg = eg = EA = EA = EA = ed = ed = ed, eg = ed = ed = ed, eg = ed, eg = ed = ed, eg = ed, eg = east = ed, - (eg = EA = ed, - (eg = east = ed, \vn / N, (2), substituting n = 2 into the above formula, we get: AD / AB = 2v2 / 2 = v2
