construct a triangle PQR in which QR=6cm and angle Q = 60degree and PR-PQ=2cm.

We have to construct a triangle with the given data as-

Step-1: Draw the base line segment QR= 6 cm. 

Step-2 : From Q, draw an angle of using compass, say ∠XQR.

Step-3 :Extend the line QX in the opposite direction as well to T. Cut a line segment QS of 2 cm from the line segment QT  extended in the opposite side of line segment XQ. Now join the point to R in order to get SR.

Step-4 : Draw perpendicular bisector AB of line segment SR. Let it intersect QX at point P. Join PQ, PR.

Thus ΔPQR is the required triangle.

The below given steps will be followed to construct the required triangle.

Step I: Draw line segment QR of 6 cm. At point Q, draw an angle of 60°, say ∠XQR.

Step II: Cut a line segment QS of 2 cm from the line segment QT extended in the opposite side of line segment XQ. (As PR > PQ and PR − PQ = 2 cm). Join SR.

Step III: Draw perpendicular bisector AB of line segment SR. Let it intersect QX at point P. Join PQ, PR.

ΔPQR is the required triangle.
