Draw a circle of radius 3 cm. Draw a tangent to the circle making an angle of 30° with a line passing through the centre.

Steps of Construction:


1. Draw a circle with center O and radius of length 3cm.


2. Draw any radius OP of this circle.


3. Extend OP to Q.


4. Draw angle AOP = 60°.



5. From A, draw angle of 90°.


6. The two lines intersect each other at B.


7. Then BA is the required tangent.
