Question

define of parallel lines ​

Answer 1

Answer:

In geometry, parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel

Step-by-step explanation:

Here, three set of parallel lines have been shown - vertical, diagonal and horizontal parallel lines.

Parallel lines in geometry

Sides of various shapes are parallel to each other. Parallel lines are represented with a pair of vertical lines between the names of the lines, such as PQ ︳︳XY.

We can see parallel lines in a zebra crossing, the lines of notebook and in railway tracks around us.
