Question

Construct an isosceles triangle ABC such that AB = 6 cm, BC = AC = 4 cm. Bisect ∠C internally and mark a point P on this bisector such that CP = 5 cm. Find the points Q and R which are 5 cm from P and also 5 cm from the line AB.

Solution


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.
