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!
