Which lines cross at a point?

Which lines cross at a point?

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

Answer: (B)

When two lines cross each other at a single point, they are called intersecting lines. That’s exactly what the question is asking for: lines that cross at a point. Parallel lines never meet, so they don’t cross. Skew lines aren’t in the same plane, so they can’t meet either. Perpendicular lines do cross at a point too, at a right angle, but “intersecting lines” is the general term for any crossing, whether or not the angle is 90 degrees. That’s why this choice best fits the idea of crossing at a point.
