ConceptConstructing a Quadrilateral When Two Adjacent Sides and Three Angles Are Known

#### Question

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:

Step I: Draw AB = 2 . 8 cm .

Step II: Construct ∠BAD = 60° .

Step III : With A as the centre and radius 3 . 3 cm, cut off AD = 3 . 3 cm .

Step IV: With D as the centre and radius 2 . 6 cm, draw an arc .

Step V : With B as the centre and radius 3 . 1 cm, draw an arc to intersect the arc drawn in Step IV at C .

Step VI: Join BC and CD to obtained the required quadrilateral .
