Question

lexi started with cd on her paper. she folded her paper so that point c was on top of point d. then, she unfolded her paper and labeled the intersection of the fold and the line - segment with point e. she used a straight edge to draw qr at an arbitrary angle through point e. finally, she drew cr through points c and r and dr through points d and r. which line segment or line is the segment bisector in this scenario? (1 point)

Explanation:

Step1: Recall segment - bisector definition

A segment bisector divides a line segment into two equal parts.

Step2: Analyze the folding process

Lexi folded the paper so that point $C$ was on top of point $D$. The intersection of the fold and the line - segment $CD$ is point $E$. The fold is the perpendicular bisector of $CD$, which means $CE = ED$. The line $\overleftrightarrow{QR}$ passes through point $E$ (the mid - point of $CD$).

Answer:

$\overleftrightarrow{QR}$
