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

#### Question

Construct a quadrilateral ABCD, given that AB = 8 cm, BC = 8 cm, CD = 10 cm, AD = 10 cm and ∠A = 45°.

#### Solution

Steps of Construction:

Step I: Draw AB = 8 cm .

$\text { Step II: Construct } \angle BAD = 45^\circ.$

Step III : With A as the centre and radius 10 cm, cut off AD = 10 cm .

Step IV: With D as the centre and radius 10 cm, draw an arc .

Step V : With B as the centre and radius 8 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 .
