Let say number is 3.5
Mark the distance 3.5 units from a fixed point O on a given line to obtain a point A such that AO = 3.5 units. From O, mark a distance of 1 unit and mark the new point as B. Find the mid-point of AB and mark that point as C. Draw a semicircle with centre C and radius 3.5. Draw a line perpendicular to AB passing through O and intersecting the semicircle at D.
