Question

In a circle of radius $4cm$, draw two radii such that the angle between them is ${120}^o$. Draw two tangents at the ends of the radii.

Answer 1

First draw a circle of radius $4cm$ with centre $O$.

Draw one radius and give it a name say $OB$.

Place the protractor on the radius centred at circle centre and make an angle of ${120}^o$ from the radius $OB$.

We got two tangents $OA$ and $OB$.

Then draw two tangents at the end points of radii.
