Question

1. what kind of relationship do $overleftrightarrow{cf}$ and $overline{gh}$ have?

congruent
parallel
skew
perpendicular

Explanation:

Step1: Recall definitions

Parallel lines are in the same plane and never intersect. Perpendicular lines intersect at a right - angle. Congruent refers to equal in size and shape, not a line - relationship here. Skew lines are non - coplanar and do not intersect. In the given rectangular prism, line segment $\overline{CF}$ and line segment $\overline{GH}$ are non - coplanar and do not intersect.

Answer:

B. Skew
