Question
Draw two concentric circle of radii 3cm and 5cm. Taking a point on the outer circle, construct the pair of tangents to the inner circle.

Answer


Steps of construction:
  1. Draw a circle with radius 3cm and centre O.
  2. Draw another circle with radius 5cm and same centre 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.
