Question
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:
Step I: Draw AB = 3 . 8 cm .
\[\text { Step II: Construct} \angle ABC = 80^\circ . \]
Step III : With B as the centre and radius 3 . 4 cm, cut off BC = 3 . 4 cm .
Step IV: With C as the centre and radius 4 . 5 cm, draw an arc .
Step V : With A as the centre and radius 5 . 3 cm, draw an arc to intersect the arc drawn in Step IV at D .
Step VI: Join AD, BC and CD to obtained the required quadrilateral .
