Step-by-step explanation:
Draw arcs on either side of a given point on the line
To construct a line perpendicular to another line through a point on the line:
Measure a length from that point to one edge of the line
Draw two intersecting arcs on either sides of the line
Draw a straight line from the intersecting point of the arcs to the point on the existing line.
The new line drawn is a perpendicular line.
The only step necessary out of the given choices is "Draw arcs on either side of a given point on the line"
