Answer:
in triangles abd and acd
angle bad=angle cad .......[perpendicular of an isosceles triangle bisects the angle from which the perpendicular is drawn]....[1]
ad=ad [self congruency] ....[2]
angle adb=angle adc [given in the question]
from [1],[2] and [3],
we can say that triangle abd is congruent to triangle acd [asa congruence test]
therefore,
bd=dc by cpct[congruent parts of congruent triangles]
