Solution

1)
1. Draw MO of length 6 cm.
2. Draw an angle of 105 degree on O and cut an arc of 4.5 cm on it. The point of intersection is R.
3. Draw an angle of 105 degree on R and draw an angle of 60 degree on M. Their point of intersection is E.
4. Join all the points.
MORE is the required quadrilateral.

2)
1. Draw PL of length 4 cm.
2. Calculate the value of L, which comes out to be 75o.
Draw an angle of 75o on L and cut an arc of 6.5 cm on it. The point of intersection is A.
3. Draw an angle of 110o on A and draw an angle of 90o on P. Their point of intersection is N.
4. Join all the points.
PLAN is the required quadrilateral.

3)
1. Draw EA of length 6 cm.
2. Draw an angle of 85o on E and cut an arc of 5 cm on it. The point of intersection is H. (R=E=85o and H=95o)
3. Draw an angle of 95o on H and cut an arc of 6 cm. Their point of intersection is R.
4. Join all the points.
HEAR is the required parallelogram.

4)
1. Draw OK of length 7 cm.
2. Draw an angle of 90o on K and cut an arc of 5 cm on it. The point of intersection is A.
3. Draw an angle of 90o on A and cut an arc of 7 cm from A. The point of intersection is Y.
4. Join all the points.
OKAY is the required rectangle.
