Question

In the given figure ,AB =BC and Angle ABD =angle CBD .prove that angle DAB =angle DCB

Answer 1

Let's consider triangle ABO and triangle CBO
AB=AC(given)

angle ABO=angle CBO(given)

OB=OB(common side)

therefore, traingle ABO=triangle CBO(by SAS rule of congruency)

angle DAB = angle ECB(by CPCT)
