Question

.
(7) Draw a circle with center O and radius 2.5 cm.Draw two radii OA and OB such that angle AOB =60º.
Measure the length of the chord ab​

Answer 1

solution:

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 60

o

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=30

0

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

solution:

HERE AD=2.5 sin30°

2.5×1/2

AB=2AD

PUT VALUE OF AD

AB=2×1/2×2.5

after cutting

remaining answer will be 2.5 cm

HOPE IT WILL WORK ✌️✌️
