Draw the following.
Q4. A parallelogram OKAY where OK = 5.5 cm and KA = 4.2 cm. Is it unique?
Given, OKAY is a parallelogram where OK = 5.5 cm and KA = 4.2 cm.
Steps of construction:
Step 1. Draw a line segment OK = 5.5 cm. Draw a ray KX from point K (With any suitable angle). Extend OK in the direction of KO.
Now we make a ray parallel to KX from O.
Step 2. With K as the center and a suitable radius, draw an arc cutting both OK and KX at P and Q respectively.
Step 3. With the same radius and O as the center, draw an arc cutting extended OK at P'.
Step 4. With P as the center, measure PQ using the compass. Using this as radius, cut the previous arc with P' as the center and mark it Q'. Draw a ray OZ passing through Q'.
Step 5. With radius = KA = 4.2 cm, cut two arcs on OZ and KX with O and K as centers respectively. These intersections points are Y and A respectively. Join Y to A.
OKAY is the required parallelogram. It is not unique as the angle can be varied keeping opposite sides parallel to each other.
