Answer:

The steps of construction are as follows:

1. Draw a circle of any convenient radius and mark its centre as O.

2. Draw one of its radius OA and draw a line perpendicular to OA at A.

3. Draw an angle of 90º at O such that it intersects the circle at B.

4. Draw a line perpendicular to OB at B and let both perpendiculars intersect at point P.

Thus, PA and PB are the required tangents.
