Step I: Draw a line l and take a point A outside it.

Step II: Place a set square PQR such that its one arm PQ of the right angle is along the line l.

Step III: Hold the set square fixed and a ruler along the edge PR opposite to the right angle of the set square.

Step IV: Holding the ruler fixed, slide the set-square along the ruler until the other arm QR reaches the point A.

Step V: Without disturbing the position of the set-square, draw a line m along the edge QR.

The line m is the required line perpendicular to line l.
