Steps of Construction:
1. Draw MO = 6 cm.
2. At O construct an angle of 105∘ and draw a ray.
3. Draw an arc of radius 4.5 cm intersecting the ray at R.
4. At R construct an angle of 105∘ and draw a ray.
5. At M construct an angle of 60∘ and draw a ray.
6. Let these two rays intersect at a point. Let it be E.
7. Quadrilateral MORE is the required quadrilateral.
