Answer» Proof,In ΔABC & ΔABD,AB = AB (Common)AC = AD (Given)∠CAB = ∠DAB (AB is bisector) Hence, ΔABC ≅ ΔABD. (by SAS congruence rule) Then, BC= BD (by CPCT) Thus, BC & BAD are equal.

Answer»

Proof,In ΔABC & ΔABD,AB = AB (Common)AC = AD (Given)∠CAB = ∠DAB (AB is bisector)

Hence, ΔABC ≅ ΔABD. (by SAS congruence rule)

Then, BC= BD (by CPCT)

Thus, BC & BAD are equal.
