Construct a quadrilateral ABCD in which AB = 7.7 cm, BC = 6.8 cm, CD = 5.1 cm, AS = 3.6 cm and C = 120°.

Steps of construction:


Step I: Draw DC = 5.1 cm.



Step II: Construct DCB = 120°.



Step III: With C as the center and radius 6.8 cm, cut off BC = 6.8 cm.



Step IV: With B as the center and radius 7.7 cm, draw an arc.


Step V: With D as the center and radius 3.6 cm, draw an arc to intersect the arc drawn in Step IV at A.


Step VI: Join AB and AD to obtain the required quadrilateral.
