Construct Perpendicular Line

This example shows how to construct a line perpendicular to another line.

Steps

  1. Start by drawing a point where the perpendicular line will intersect.

    Step 1
  2. Draw two points of equal distance away from the initial point along the line. The easiest way to do this is to draw a circle at the initial point and draw two points where the circle intersects the line.

    Step 2
  3. Draw an arc upwards with a radius equal to the distance between the two outer points.

    Step 3
  4. Repeat this process for the other point and mark where the two arcs intersect.

  5. Draw a line from the point of intersection to the initial point.

    Step 5

    We have finished constructing a perpendicular line.
