Lines in the same plane that never intersect are called?

• A. Skew lines
• B. Intersecting lines
• C. Parallel lines
• D. Perpendicular lines

Answer: (C)

Lines that lie in the same plane and never meet are parallel lines. The defining feature is that they run alongside each other with a constant distance apart and do not intersect no matter how far you extend them. This sets them apart from intersecting lines, which cross at a point, and from perpendicular lines, which cross at a right angle. Skew lines, while they also don’t meet, aren’t in the same plane, so they don’t fit the description of being in the same plane.
