What is parallel line and perpendicular line? Give real life example with neat figure.
- Parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel.
- Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it.
