Answer 2

Answer:

AF = (1/3) AC.

Step-by-step explanation:

(i) In ΔADG,

E is the mid-point of AD and EF || DG.

∴ EF bisects AG, i.e F is the mid-point of AG

AF = FG.

(ii) In ΔBCF,

D is the mid-point of BC and DG || BF,

∴ DG bisects FC, i.e G is the mid-point of FC.

FG = GC

From (i) & (ii), we get

AF = FG = GC

AC = AF + FG + GC

     = AF + AF + AF

     = 3AF

AF = AC/3

AF = (1/3) AC.

Hope it helps!
