Answer 2

Answer:

In figure 2.22, ray AE || ray BD, ray AF is the bisector of ∠EAB and ray BC is the bisector of ∠ABD.

Proved that line AF || line BC.

Step-by-step explanation:

ray AE || ray BD

∠BAE  = ∠ABD

=> ∠BAF + ∠EAF = ∠ABC + ∠DBC

=> x  + x  = y + y

=> 2x = 2y

=> x = y

∠BAF = x

∠ABC  = y

=> ∠BAF = ∠ABC

AF ║ BC
