Let’s take an example


  1. Given a line l
    with point P not on it

  1. With P as center, and any radius,
    draw an arc intersecting the line at points A and B
    Drawing perpendicular to a line through a point not on it – Using ruler and compass - Part 2
  2. Now with A as center, and same radius  draw an arc.
    With B as center, and same radius as before, draw an arc

Drawing perpendicular to a line through a point not on it – Using ruler and compass - Part 3

 

  1. Mark the point of intersection of the two arcs as point Q

          Join P & Q.

Drawing perpendicular to a line through a point not on it – Using ruler and compass - Part 4

 

∴ PQ is the line perpendicular to line l
