Two lines cross each other at a point. What is this relationship called?

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

Answer: (C)

Lines that cross each other share a point where they meet. This is called intersecting lines. The key idea is that they do meet at a point, which distinguishes them from parallel lines that never meet. If the crossing happens at a right angle, that specific situation is called perpendicular, but crossing at any angle still makes them intersecting.
