Question

in the figrue, O is the centre of the circle. Find the length of CD ,if AB=5cm​

Answer 1

Step-by-step explanation:

In given figure O is the center of circle .And lenth AB=5 cm and ∠AOB=∠COD=55 ^0

In ΔAOB and ΔCOD

∠AOB=∠COD=55 ^0

(Given )

OA=OD (Radius)

OB=OC (Radius)

∴ΔAOB≅ΔCOD

∴AB=CD=5cm Given AB=5 cm

So CD=5 cm
