Answer 1

Given : AD=DC
To prove : BD=DC
Proof:
The opposite angle of AD is angle ABD and opp. of DC is angle DBC
As AD = DC
Angle ABD = angle DBC
Now in ∆ ABD & ∆ DBC
Angle ABD = Angle DBC
AD = DC
BD = BD
By S. A. S ∆ ABD is Congruent to ∆ DBC
By cpctc = AD = BD
As AD = DC
BD = DC
..... (Hence proved)
