Construct a parallelogram PQRS in which QR=6cm, PQ=4cm and ∠PQR = 60°.

The given parallelogram PQRS can be drawn as follows:

Step 1: Draw a line segment QR = 6 cm.

Step 2: At Q, draw ∠RQX = 60°.

Step 3: Cut PQ = 4 cm on ray QX

Step 4: Draw an arc from P at a radius of 6 cm.

Step 5: Now, take 4 cm from R and cut the arc drawn in step 4 and the point of intersection of arcs is S.

Step 6: Now, join SP and SR.

Step 7: PQRS is the required parallelogram.
