Step-by-step explanation:
Steps of Construction :
1. Draw a circle of radius 4cm with centre O.
2. A point P was marked outside the circle such that, OP = 7cm.
3. P to O was joined.
4. Perpendicular bisector of PO was found to be M.
5. With MO as radius and M as center a circle was drawn touching the previous drawn circle.
6. Point of intersections of two circles were marked to be Q and R respectively.
7. P was joined to Q and R respectively.
Therefore, required tangents will be PQ and PR.
