angle abc= angle acb
means, angle 1+ angle4= angle3 + angle 2
angle 3= angle 4
they will get cancled
hence angle 1= angle 2

Simplest method
angle ABC = angle ACB
angle 4 + angle 1 = angle 2 + angle 3
angle 4 + angle 1 = angle 2 + angle 4
(angle 1 = angle 2 )
angle 1 = angle 2
BD = DC
( side opposite to similar angle is equal )
angle ABC = angle ACB
angle 4 + angle 1 = angle 2 + angle 3
angle 4 + angle 1 = angle 2 + angle 4
(angle 1 = angle 2 )
angle 1 = angle 2
BD = DC
( side opposite to similar angle is equal )
