Question Analysis

This question involves the concept of parallel lines in geometry. The main focus is on understanding the characteristics and definitions of parallel lines and differentiating them from other types of lines such as perpendicular, skew, and intersecting lines.

Key Concept Explanation:

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

Option Analysis

Option B aligns with the standard definition of parallel lines in a plane.

The other options are incorrect:

Option A: it describes perpendicular lines, not parallel lines. The key here is to understand the difference between perpendicular and parallel based on the angle of intersection.

Option C: it refers to skew lines. The distinction between coplanar and non-coplanar is crucial in differentiating parallel from skew lines.

Option D: it is incorr...
