Construct a quadrilateral ABCD, in which AD = 3.5 cm, AB = 4.4 cm, BC = 4.7 cm, ∠A = 125° and ∠B= 120°.
Steps of construction:
Step I: Draw AB = 4 . 4 cm .
Step II: Construct \angleBAD = 125\textdegree at A .
Step III : With A as the centre and radius 3 . 5 cm, cut off AD = 3 . 5 cm .
Step IV: Construct ∠ABC = 120° at B .
Step V : With B as the centre and radius 4 . 7 cm, cut off BC = 4 . 7 cm .
Step VI: Join CD .
The quadrilateral so obtained is the required quadrilateral .
