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.
