Question Analysis

This question involves the determination of the relationship between two lines within the context of a 3D figure. The main focus is on applying the definitions of skew lines, parallel lines, and intersecting lines to identify the correct relationship between these two lines.

Key Concept Explanation:

Skew lines are defined as non-coplanar lines, meaning they do not lie in the same plane, and they do not intersect each other.

Parallel lines are defined as coplanar lines that do not intersect each other, no matter how far they are extended.

Intersecting lines are defined as coplanar lines that cross each other at a single point.

Step-by-Step Solution:

EH and DH share the common point H, fulfilling...
