Skew lines are a pair of lines that are non-intersecting, non-parallel, and non-coplanar.
What is Skew lines definition?
Skew lines are a pair of lines that are non-intersecting, non-parallel, and non-coplanar. This implies that skew lines can never intersect and are not parallel to each other. For lines to exist in two dimensions or in the same plane, they can either be intersecting or parallel. As this property does not apply to skew lines, hence, they will always be non-coplanar and exist in three or more dimensions.
Skew Lines Example
In real life, we can have different types of roads such as highways and overpasses in a city. These roads are considered to be on different planes. Lines drawn on such roads will never intersect and are not parallel to each other thus, forming skew lines.
Skew Lines in 3D
Skew lines will always exist in 3D space as these lines are necessarily non-coplanar.
In the figure given below 'a' and 'b' are skew lines.
Therefore, skew lines are a pair of lines that are non-intersecting, non-parallel, and non-coplanar.
