you can coordinate parallel because parallel lines never touch or cross
A parallelogram is a 4 sided quadrilateral that has two pairs of parallel sides and 4 interior angles that add up to 360 degrees
Then they are not parallel, nor skew (in 3D).
One pair of parallel sides of unequal length, the other two sides being of equal length but not parallel. there are other properties that can be derived from these.
They are parallel to each other is the best choice to describe the bases of a cylinder.

It is a 3D shape that looks like a tin can with opposite parallel circular faces and a rounded body.
A vertex? In non-euclidean geometry: A two distinct parallel lines intersect in the "Infinity zone"
2 lines the same width apart are parallel.
Depends how much is being added to which x-coordinate: If a constant amount is added to every x-coordinate, the polygon is translated (parallel to the x-axis). [This first possibility is what I think you are really asking, however:] If an amount is added which depends linearly upon the y-coordinate of the x-coordinate, the polygon is sheared (parallel to the x-axis). If an amount is added which depends linearly upon the x-coordinate, the polygon is stretched (parallel to the x-axis). If a random amount is added, the polygon is randomly transformed.

no
Yes, all vertical lines are parallel, for a given coordinate system.
Do you mean "Why might a parallel line algorithm be needed?" or "What properties does a parallel line algorithm need to have?".
Two pairs of parallel lines.
