Two lines that never meet and stay the same distance apart are called

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

Answer: (C)

If two lines never meet and stay the same distance apart, they are parallel lines. This means they run in the same direction and, when you measure the perpendicular distance between them at any point, that distance is constant.

Skew lines are non-parallel lines in space that don’t lie in the same plane, so they don’t have a fixed distance everywhere. Perpendicular lines intersect at a right angle, so they do meet. Intersecting lines share a point of crossing, so they do not stay apart.
