Answer 4

cd=db given

Answer 5

in cdb two sides are equal so angle 1= angle 2

Answer 6

angle acd= angle 1 --------> 1
as cd bisects angle acb
similarly
angle 2=angle abd ----------> 2
we proved angle 1= angle 2

Answer 7

angle acd=angle 1= angle 2=angle abd

Answer 8

acd=abd
1+acd=abd+1
as angle 1 = angle 2 so replace 1 by 2 on right side
1+acd=2+abd
acb=abc
so 2 angles are equal so triangle is isosceles
