आकृति

उत्तर

Step of Construction:

  1. Draw a line segment OT = 6 cm.
  2. Draw a circle of radius 2.5 cm taking O as centre.
  3. Draw a perpendicular bisector EF of OT which meets OT at M.
  4. Taking MT as radius and M as centre, draw a circle C2 which intersects C1 at Pand Q.
  5. Join TP and TQ.
    Hence, TP and TQ are the required tangents.
