**Question 1.****Construct a quadrilateral ABCD in which AB = 3.8 cm, BC = 3.4 cm, CD = 4.5 cm, AD = 5 cm and ∠B = 80°.****Solution:****Steps of construction :**

(i) Draw a line segment AB = 3.8 cm.

(ii) At B, draw a ray BX making an angle of 80° and cut off BC = 3.4 cm.

(iii) With centre A and radius 5 cm and with centre C and radius 4.5 cm, draw arcs which intersect each other at D.

(iv) Join CD and AD.

ABCD is the required quadrilateral.

**Question 2.****Construct a quadrilateral ABCD given that AB = 8 cm, BC = 8 cm, CD = 10 cm, AD = 10 cm and ∠A = 45°.****Solution:****Steps of construction :**

(i) Draw a line segment AB = 8 cm.

(ii) At A, draw a ray AX making an angle of 45° and cut off BC = 8 cm.

(iii) With centre A and C and radius 10 cm, draw arcs intersecting each other at D.

(iv) Join AD, CD.

Then ABCD is the required quadrilateral.

**Question 3.****Construct a quadrilateral ABCD in which AB = 7.7 cm, BC = 6.8 cm, CD = 5.1 cm, AD = 3.6 cm and ∠C = 120°.****Solution:****Steps of construction :**

(i) Draw a line segment BC = 6.8 cm.

(ii) At C, draw a ray CX making an angle of 120° and cut off CD = 5.1 cm.

(iii) With centre B and radius 7.7 cm and with centre D and radius 3.6 cm draw arcs which intersect each other at A.

(iv) Join AD and AB.

Then ABCD is the required quadrilateral.

**Question 4.****Construct a quadrilateral ABCD in which AB = BC = 3 cm, AD = CD = 5 cm and ∠B = 120°****Solution:****Steps of construction :**

(i) Draw a line segment AB = 3 cm.

(ii) At B, draw a ray BX making an angle of 120° and cut off BC = 3 cm.

(iii) With centres A and C, and radius 5 cm, draw arcs intersecting each other at D.

(iv) Join AD and CD.

Then ABCD is the required quadrilateral.

**Question 5.****Construct a quadrilateral ABCD in which AB = 2.8 cm, BC = 3.1 cm, CD = 2.6 cm and DA = 3.3 cm and ∠A = 60°.****Solution:****Steps of construction :**

(i) Draw a line segment AB = 2.8 cm.

(ii) At A draw a ray AX making an angle of 60° and cut off AD = 3.3 cm.

(iii) With centre B and radius 3.1 cm and with centre D and radius 2.6 cm, draw arc which intersect each other at C.

(iv) Join CB and CD.

Then ABCD is the required quadrilateral.

**Question 6.****Construct a quadrilateral ABCD in which AB = BC = 6 cm, AD = DC = 4.5 cm and ∠B = 120°.****Solution:****Steps of construction:**

The construction is not possible to draw as arcs of radius 4.5 cm from A and C, do not intersect at any point.
