Question

0.1
1 In the adjoining figure, AB = AC, CP || BA and AP is the bisector of CAD.
Prove that:
1)angle PAC =angle BCA
2) ABCP is a parallelogram.
(Hint:angle CAD = angle ABC +angle ACB = 2 angle ACB (Why)?

And so, anglePAC =1/2 angle CAD=angle ACB
Therefore AP||BC)

​

Answer 1

Answer:

bcad is adjoining figure angle

bca is a congruent to bcad

cad is congruent to bca
