Draw two concentric circles of radius 3 cm and 5 cm. Taking a point on the outer circle, construct the pair of tangents to the inner circle.
Steps of construction:
1. Draw a circle with radius 3 cm and centre O.
2. Draw another circle with radius 5 cm and same centre O. O’
3. Take a point P on the circumference of larger circle and join O to p.
4. Taking OP as diameter draw another circle which intersects the smallest circle at A and B.
5. Join A to P and B to P.
Hence AP and BP are the required tangents.
