**Question 5.**

**Solution:**

Steps of Construction :

(i) Draw a line segment RS = 5 cm.

(ii) With centre R and S, radius 6 cm. each, draw arcs intersecting each other at R

(i) Draw a line segment AB = 3.4 cm.

(ii) With centre A and radius 5.7 cm. and with centre B and radius 4 cm., draw arcs intersecting each other at D.

(iii) Join BD and AD.

(iv) Again with centre A and radius 8 cm and with centre D and radius 3 cm., draw arcs intersecting each other at C.

(v) Join AC, BC and DC. ABCD is the required quadrilateral

**Question 7.**

**Solution:**

Steps of Construction :

(i) Draw a line segment AB = 3.5 cm.

(ii) At B, draw a ray BX making an angle of 120° using protractor and cut off BC = 3.5 cm

(iii) With centres A and C and radius 5.2 cm, draw arcs intersecting each other at D.

(iv) Join CD and AD. ABCD is the required quadrilateral.

**Question 8.**

**Solution:**

Steps of Construction :

(i) Draw a line AB = 2.9 cm.

(ii) At A, draw a ray AX making an angle of 70° with AB. Using protractor and cut off AD = 3.4 cm.

(iii) With centre B and radius 3.2 cm and with centre D and radius 2.7 cm., draw arcs intersecting each other at C.

(iv) Join BC and DC. ABCD is the required quadrilateral.

**Question 9.**

**Solution:**

Steps of Construction

(i) Draw a line segment BC = 5 cm.

(ii) At B, draw a ray BX making an angle of 125° and cut off BA = 3.5 cm.

(iii) At C, draw a ray CY making an angle of 60° and cut off CD = 4.6 cm

(iv) Join AD. ABCD is the required quadrilateral.

**Question 10.**

**Solution:**

Steps of Construction :

(i) Draw a line segment QR = 5.6 cm.

(ii) At Q, draw a ray QX making an angle of 45° and cut off QP = 6 cm.

(iii) At R, draw a ray RY making an angle of 90° and cut off RS = 2.7 cm.

(iv) Join SP PQRS is the required quadrilateral.

**Question 11.**

**Solution:**

Steps of Construction :

∠A = 50°, ∠B = 105° and ∠D = 80°

and ∠A + ∠B + ∠C + ∠D = 360°

=> 50° + 105° + ∠C + 80° = 360°

=> ∠C + 235° = 360°

=> ∠C = 360° – 235°

=> ∠C = 125°

(i) Draw a line segment AB = 5.6 cm.

(ii) At B, draw a ray BY making an angle of 105° and cut off BC = 4 cm.

(iii) At C, draw a ray CZ making an. angle of 125° and at A, a ray AX making an angle of 50° intersecting each other at D.

then ∠D = 80°

ABCD is the required quadrilateral.

**Question 12.**

**Solution:**

∠P + ∠Q + ∠R + ∠S = 360°

100° + ∠Q + 100° + 75° = 360°

=> ∠Q + 275° = 360°

=> ∠Q = 360° – 275°

∠Q = 85°

Steps of Construction :

(i) Draw a line segment PQ = 5 cm.

(it) At Q, draw a ray QX making an angle of 85° and cut off QR = 6.5 cm.

(iii) At R, draw a ray making an angle of 100° and at P, another ray making an angle of 100° which intersect each other at S. then ∠S = 75°

PQRS is the required quadrilateral.

**Question 13.**

**Solution:**

Steps of Construction :

(i) Draw a line segment AB = 4 cm.

(ii) At B, draw a ray BX making an angle of 90°.

(iii) From A, draw an arc of 5 cm. radius intersecting BX at C.

(iv) Join AC.

(v) At C, draw a ray CY making an angle of 90°.

(vi) From A, draw an arc of radius 5.5 cm. which intersects CY at D.

(vii) Join AD.

ABCD is the required quadrilateral.
