FAQs on Worksheet: Parallel and Intersecting Lines

1. What are parallel lines?
Ans. Parallel lines are lines in a plane that never meet or intersect, no matter how far they are extended. They are always the same distance apart.
2. What are intersecting lines?
Ans. Intersecting lines are lines that cross each other at one point. The point where they meet is called the point of intersection.
3. How can you identify parallel and intersecting lines in a diagram?
Ans. In a diagram, parallel lines can be identified by their equal distance apart and the lack of intersection. Intersecting lines will cross each other and have a point where they meet.
4. What is the difference between parallel lines and perpendicular lines?
Ans. The main difference is that parallel lines never intersect and remain equidistant, while perpendicular lines intersect at a right angle (90 degrees).
5. Can two lines be both parallel and intersecting?
Ans. No, two lines cannot be both parallel and intersecting. If lines are parallel, they will never intersect; if they intersect, they cannot be parallel.
