Question

1. Draw a circle with centre O and radius 2.5 cm. Draw two radii OA and OB such that
angle AOB = 60°. Measure the length of the chord AB.​

Answer 1

Step-by-step explanation:

1. Draw a circle, taking centre as O and radius equal to 2.5 cm.

2. Join OA, where A is any point on the circle

3. Draw ∠AOB equal to 60o

4. Now, join AB.

As shown in the figure, it can be seen that by pointing out the point D

and as we can see that the central angle gets bisected thus making ∠AOD=300 

 and on measuring as shown in image we get, AB =2.5cm
