To construct a perpendicular line that is not a perpendicular bisector, you would place the compass needle on one end of a line segment and draw an arc that intersects the line at some point without necessarily going through the midpoint.
From the given descriptions, the diagram that represents a step in constructing a perpendicular line that is not a perpendicular bisector is:
The last response: "A line segment has 2 end points labeled A and B. A compass has its needle on the right end point, B, and its pencil is placed about two thirds of the way along line segment."
This step involves drawing an arc from one endpoint (point B), indicating that you could construct a perpendicular line at that endpoint rather than at the midpoint, which is characteristic of a perpendicular bisector.
