In this scenario, Lexi folded her paper so that point C was on top of point D, creating a fold line that would be the angle bisector of segment CD. The point where the fold intersects segment CD is labeled E, indicating that it divides the segment into two equal parts.
Since the fold (which intersects segment CD at point E) acts as a segment bisector, the line segment or line that serves as the segment bisector in this scenario is:
CD¯¯¯¯¯¯¯¯
So the correct response is:
CD¯¯¯¯¯¯¯¯
