Draw a line segment AB and take a point P which is not on AB and draw a perpendicular to AB through P. 6 | experimental...

Draw any line segment bar(PQ). Take any point R not on it. Through R, draw a perpendicular to bar(PQ) (use ruler and set-square)

Draw any line segment bar(AB). Mark any point M on it. Through M, draw a perpendicular to bar(AB). (use ruler and compasses)

Draw a line l. Take any point P on the line. Using a set square, draw a line perpendicular to the line l at the point p.

Draw a line segment AB of length 5.5 cm. Bisect it using a compass and ruler.
