Steps of construction:

  1. Draw a line segment AB = 6 cm.
  2. With centers A and B and radius 4 cm, draw two arcs which intersect each other at C.
  3. Join CA and CB.
  4. Draw the angle bisector of angle C and cut off CP = 5 cm.
  5. A line m is drawn parallel to AB at a distance of 5 cm.
  6. P as centre and radius 5 cm, draw arcs which intersect the line m at Q and R.
  7. Join PQ, PR and AQ.
    Q and R are the required points.
