Draw a circle of radius 4 cm. Draw tangent to the circle making an angle of 60° with a line passing through the centre.

Steps of Construction:


1. Draw a circle with center O and radius of length 4cm.


2. Draw any radius OP of this circle.


3. Extend OP to Q.


4. Draw angle AOP = 30°.



5. From A, draw angle of 90°.


6. The two lines intersect each other at B.



7. Then BA is the required tangent as angle ABP = 60°
