1.Draw AB=5 cm line

2.From 'A' draw AC =7cm

3.From 'B' draw arc BC = 5.5 cm , Intersection point 'C'

4.From 'A' draw Arc AD = 5.5 cm

5. From 'C' draw Arc CD = 4.5 cm , Intersection point 'D'

6. Join ¯BC,¯DL,¯AD, Now required quadrilateral ABCD formed.

Question 5

Sol :











Steps.

1. Draw BC=6 cm line

2. At 'C' Draw C= 90 line upto ¯DC=4 cm name point 'D'

3. From 'B' Draw B=45 line 

4. From 'D' draw D=120 Line , Intersection point is 'C '

5. Join ¯BC,¯CD Now required quadrilateral ABCD formed.


Question 6

Sol :












Steps.

1.Draw PQ = 4cm line 

2. Draw Q = 90 line up ¯QR= 6cm and mark 'R'

3.Draw P60 line

4.Draw  R=120 line , Intersection Point is 'S'

5. Join ¯PS,¯SR, Now required quadrilateral PQRS formed
  

Question 7

Sol :










Steps.

1. Draw AB=5 cm line

2. Draw B=60 line from B

3.Draw Cut B=60 Line with Arc of BC = 4.2 cm point 'C'

4.At 'A' Draw A=90 and at a distance of AD = 3.5cm mark 'D'

5.Join ¯DC Now required quadrilateral ABCD is formed.

Question 8 

Sol :
