Q1 of 805 Page 18

Construct a quadrilateral ABCD given that AB = 4 cm, BC = 3 cm, ∠A = 75°, ∠B = 80° and ∠C = 120°.

Step 1: Draw the side AB = 4 cm

Step 2: Draw = 75°

Step 3: Draw = 80°

Step 4: With B as centre and radius equal to 3 cm draw an arc and name the point as C

Step 5: With C as centre ,construct an angle 120° and mark the point of intersection of line AX and the angle 120° as point D

Step 6: Join the points C and D

ABCD is the required quadrilateral

Construct a quadrilateral BDEF, where DE = 4.5 cm, EF = 3.5 cm, FB = 6.5 cm, ∠F = 50° and ∠E = 100°.

Construct a quadrilateral ABCD where AB = 5.5 cm, BC = 3.7 cm, ∠A = 60°, ∠B = 105° and ∠D = 90°.

Construct a quadrilateral PQRS where PQ = 3.5 cm, QR = 6.5 cm, ∠P = ∠R = 105° and ∠S = 75°.
