8 Draw an Arc Through Three Points

  1. Establish three random points. (Under normal conditions, these points will not be random.)
  2. Draw two lines to connect the points.
  3. Bisect the two lines and create perpendicular lines.
  4. Where the two perpendicular lines cross becomes the radius point for the arc.
  5. Set your compass from the established radius point to one of the three points.
  6. Swing the arc through the points.
