Question

5. In the given figure, AB = BC and ZABO = 2CBO, then prove that :
а)triangle АОВ = triangle СОВ
b) angleDAB = angleECB.​

Answer 1

Step-by-step explanation:

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)
