Question
Construct a pair of tangents to a circle of radius 4 cm from a point P lying outside the circle at a distance of 6 cm from the centre.
Solution
Steps of Construction:
- Construct a circle of radius 4 cm.
- Take a point P, 6 cm away from the centre of the circle.
- Join OP.
- Draw a perpendicular bisector of OM which intersects OP at M.
- Taking M as a centre and OM as the radius, draw another circle which intersects the previous circle at A and B.
- Join PA and PB. PA and PB are the required tangents.
