Final answer:
A real-world example of skew lines is railroad tracks. Skew lines are lines that do not intersect and are not parallel. In the case of railroad tracks, the tracks are not parallel but do not intersect.
Step-by-step explanation:
A real-world example of skew lines is railroad tracks. Skew lines in geometry are lines that do not intersect and are not parallel. In the case of railroad tracks, the tracks are not parallel as they gradually converge in the distance.
However, the tracks do not intersect.
