Start with a line segment PQ that we will copy. Step 1. Mark a point R that will be one endpoint of the new line segment. Step 2. Set the compasses' point on the point P of the line segment to be copied. Step 3. Adjust the compasses' width to the point Q. The compasses' width is now equal to the length of the line segment PQ.How do you copy a line segment?
The key to copying a given line segment is to open your compass to the length of the segment; then, using that amount of opening, you can mark off another segment of the same length. Here’s the proof diagram.How do you construct a line segment?
How to construct a Line Segment Bisector AND a Right Angle. using just a compass and a straightedge. Steps: Place the compass at one end of line segment. Adjust the compass to slightly longer than half the line segment length. Draw arcs above and below the line. Keeping the same compass width, draw arcs from other end of line.
