When a transversal line intersects by two or more parallel lines in the same plane, the series of angles are drawn. Parallel line examples in real life are railroad tracks, the edges of sidewalks, marking on the streets, zebra crossing on the roads, the surface of pineapple and strawberry fruit, staircase and railings, etc. When you close your notebook, then you will see that lines are not only parallel on each page of the notebook but they are parallel from page to the page also. Notebooks are huge collections of parallel lines. Buildings are constructed with walls parallel to each other, ceilings are parallel to floors of the building and one building is usually constructed parallel to the other building on the same block. The parallel line is widely used in the construction industry. For example, opposite sides of squares, rectangles, and parallelograms are parallel to each other. Parallel lines help us to understand the path of the objects and sides of the various shapes. No matter how far you extend the two parallel lines they will never meet or intersect each other.
Parallel lines are two straight lines that are always away from each at the same distance. Two parallel lines are represented as \in the given plane. Lines which do not have any common intersection point or cross each other are considered as parallel lines.
Two lines are said to be parallel to each other if they never meet or cross each other in a plane.
