Steps to draw a square
(1) Draw a line segment AB of length 5cm
(2) Place your set square such that the corner of the set square is at the end of the line segment
(3) Holding the set square in place measure and draw a line(5m) so that you have made a perpendicular line and mark the point as D
(4) Repeat the step-3 at B and mark the point as C
(5) Join CD thus a square of length of 5cm is formed
Steps to draw a parallelogram
(1) Draw a line segment AB of length 7cm
(2) Place your 45o set square such that the corner of the set square is at the end of the line segment
(3) Holding the set square in place measure and draw a line(7m) so that you have made a line and mark the point as D
(4) Expand the line segment AB at B and repeat the step-3 at B and mark the point as C
(5) Join CD thus a parallelogram of length of 7cm is formed
