|After doing this||Your work should look like this|
|Start with a line and point K on that line.|
|1||Set the compasses' width to a medium setting. The actual width does not matter.|
|2||Without changing the compasses' width, mark a short arc on the line at each side of the point K, forming the points P,Q. These two points are thus the same distance from K.|
|3||Increase the compasses to almost double the width (again the exact setting is not important).|
|4||From P, mark off a short arc above K|
|5||Without changing the compasses' width repeat from the point Q so that the the two arcs cross each other, creating the point R|
|6||Using the straight edge, draw a line from K to where the arcs cross.|
|7||Done. The line just drawn is a perpendicular to the line at K|
