Let’s take an example

 

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

2.Place set square on the line so that line is exactly above the set-square

Drawing perpendicular to a line through a point not on it – Using ruler and set-square - Part 2



  1. Put ruler on the hypotenuse side of the set square

  2. Keeping the ruler in the same position,
    slide the set-square till one end of the set-square passes through point P

  3.  Draw a line along the edge of the set square, keeping set-square firm
    Let the line intersect line l at Q

Thus, PQ is the perpendicular to l
