Any irregular polygon with 4 or more sides can have only one pair of parallel sides.
For example, a child's drawing of the silhouette of a house (the base, two walls and a triangular roof) is a pentagon and the two walls are the 1 pair of parallel sides.

In three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew lines is the pair of linesthrough opposite edges of a regular tetrahedron.
No, a tv is a 3-dimensional object. A pair of parallel lines are 1-dimensional objects in a 2-dimensional plane.No, a tv is a 3-dimensional object.

Parallel lines are two 1-dimensional objects that do not meet. Parallel planes are two 2-dimensional objects that do not meet.
Yes, in plane geometry parallel lines continue forever. However, in polar geometry (3 dimensions, as in Earth longitudinal lines), parallel lines eventually intersect at the poles of the sphere,
Parallel lines by definition never cross each other.
