If two lines are never going to meet, they are referred to as which?

• A. Parallel
• B. Similar
• C. Perpendicular
• D. Intersecting

Answer: (A)

Two lines that never meet are parallel. They run in the same direction and stay the same distance apart at every point, which means they do not intersect. In algebraic terms, parallel lines have the same slope, so their angles are equal and they never cross. This is different from perpendicular lines, which do meet at a right angle; and from intersecting lines, which cross at a point. The term you’re looking for is parallel.
