Give examples of parallel lines observed in nature and technology.

Parallel straight lines are straight lines that lie in the same plane and never intersect, no matter how much they continue. In nature, the phenomenon of parallel lines is also found, for example: trees, their trunks grow parallel to each other. And in technology, an example is possible: train rails. They will always be strictly parallel to each other and will never intersect with each other. You can also give an example of buildings. The high-rise buildings stand each separately, being a parallel line for the neighboring building.
