Solution
Steps of construction: (i) Draw a line segment AC=6cm (ii) Bisect AC at O. (iii) At O, draw a ray XY making an angle of 75o at O. (iv) From OX and OY, cut off OD=OB=4/2=2cm (v) Join AB,BC,CD and DA Thus, ABCD is the required parallelogram. On measuring one of the shorter sides, we get AB=CD=3cm
