The two pairs of parallel planes are ABCD and EFGH, ADEH and BCFG and the only segment parallel to BCGF is ADEH
Parallel, perpendicular and skew lines
From the given figure, we need to determine the line that is parallel to AB.
The parallel lines have no angles between them and are opposite to each other. The lines that are parallel to AB are CD, EF, and GH
Angles that are skewed to CD are those that are neither parallel nor perpendicular. The skewed lines to CD are FG and EH
