4 Bisect an Angle

  1. Set your compass to a radius of reasonable distance inside the angle and swing it from the vertex to create an arc inside the angle.
  2. . Draw a line (chord) from the 2 points that cross the lines that make the angle.
  3. Now, bisect the line (chord). You can use the vertex as one point, so you only need arc outside the chord. Set your compass to approximately ¾ of the length of the line.
  4. Keeping this distance set on your compass, swing arcs from both ends of the line.
  5. Draw a line through the vertex to the intersection of the arcs.
