Question

Answer these please to the below question

Answer 1

Hey mate:))

Your answer is here:-

In Isosceles triangle ABC,
AB=AC. ( Given)
ACB = ABC. (angle opposite to equal side)
Also in isosceles triangle BCD,
BD=DC
BCD = CBD. ( angle opposite to equal sides are equal)
ACB + BCD = ABC + CBD
ACD = ABD
Hence, ABD = ACD

Answer 2

from triangle ABC
AB=AC (given)

So,angle ABC=ACB (angle opp.....)

from BCD
BD=DC (Given)
ANGLE BCD = CBD (angle opp....)

So,angle ABC+CBD=ACB+BAD
SO,angleABD=ACD
