Solution
Steps of construction: (i) Draw a line segment AB=6cm (ii)At A, draw a ray AX making an angle of 45o and cut off AD=6cm (iii)With centre B and radius 3.6cm and with centre D and radius 5cm, draw two arcs intersecting each other at C. (iv) Join BC and DC. Thus, ABCD is the required quadrilateral. On measuring ∠BCD, it is 60o
