Which lines cross at a point?

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

Answer: (C)

Intersecting lines cross at a point. When two lines meet in the same plane at exactly one point, they are called intersecting lines. They can meet at any angle. Parallel lines never meet, so they don’t cross at a point. Skew lines aren’t in the same plane, so they don’t cross either. Perpendicular lines do cross at a point, but that’s a specific kind of intersecting line where the angle is a right angle. So the general term for lines that cross at a point is intersecting lines.
