* Example**: *

Construct a parallelogram *ABCD* with sides *AB =* 4 cm and *AD* = 5 cm and angle *A* = 60˚.

* Solution: *

Step 1 : Construct a line segment *AB* = 4 cm. Construct a 60˚ angle at point *A*.

Step 2 : Construct a line segment *AD* = 5 cm on the other arm of the angle. Then, place the sharp point of the compasses at *B* and make an arc 5 cm above *B*.

Step 3 : Stretch your compasses to 4 cm, place the sharp end at *D* and draw an arc to intersect the arc drawn in step 2. Label the intersecting point *C.* Join *C* to *D* and *B* to *C* to form the parallelogram *ABCD*.
