FAQs on Parallel and Intersecting Lines Video Lecture - Mathematics (Ganita Prakash) Class 7 - New NCERT

1. What are parallel lines?
Ans. Parallel lines are lines in a plane that do not intersect or meet at any point, no matter how far they are extended. They maintain a constant distance apart and have the same slope.
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. These lines have different slopes.
3. How can you identify if two lines are parallel?
Ans. To identify if two lines are parallel, you can check their slopes. If the slopes of the two lines are equal, then the lines are parallel. Alternatively, in a coordinate plane, if the lines have the same y-intercept and slope, they are parallel.
4. What is the significance of parallel and intersecting lines in real life?
Ans. Parallel and intersecting lines are significant in various fields such as architecture, engineering, and design. For instance, parallel lines are crucial in creating structures that require uniform spacing, while intersecting lines can help in designing layouts and pathways.
5. Can two lines be both parallel and intersecting?
Ans. No, two lines cannot be both parallel and intersecting. If two lines are parallel, they will never meet, while intersecting lines by definition cross each other at one point. Thus, they are mutually exclusive properties.
