Bisecting a Line Segment

Bisecting a Line Segment. You want to bisect line segment PQ. Step 1: Set the compass width to a approximately two thirds the line length. The actual width does not matter as long as it is more than half. Step 2: Without changing the compass width, draw an arc above and below the line.

  1. Bisecting a Line Segment

  2. You want to bisect line segment PQ.

  3. Step 1:Set the compass width to a approximately two thirds the line length. The actual width does not matter as long as it is more than half.

  4. Step 2:Without changing the compass width, draw an arc above and below the line.

  5. Step 3: Again without changing the compass width, place the compass point on the the other end of the line. Draw an arc above and below the line so that the new arcs cross the first two.

  6. Step 4: Using a straightedge, draw a line between the points where the arcs intersect.

  7. Step 5: Label the points on the new segment or line.

  8. Test your skill!
