Following are the steps of Construction:
(i) Construct a line segment
\[AB\text{ }=\text{ }6.5\text{ }cm.\]
(ii) At the point A, construct a ray which makes an angle 750 and cut off
\[AD\text{ }=\text{ }4\text{ }cm.\]
(iii) Construct the bisector of ∠DAB.
(iv) Construct the perpendicular bisector of AB which intersects the angle bisector at the point C.
(v) Now join CB and CD.
Hence, ABCD is the required quadrilateral.
