It is called the "vanishing point". Your question is about the usefulness of vanishing points when drawing horizontal lines in a painting, and the vertical features of whatever you are painting. It's something you learn in Art lessons.
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle. Apexvs geometry 2nd sem -- false.
"Parallel" refers to the relationship between two lines, not to a single line. Two lines are said to be parallel, or one line is parallel TO ANOTHER, if they are in the same plane, and are always at the same distance from each other, that is, as you move along one line, the distance to the other line is always the same - they don't cross, or get away from one another.
If the question refers to a single completely geometrically straight line of finite length in a plane, then a straight line will have two lines of symmetry. One symmetry line is perpendicular to the line being discussed and one symmetry line coincides with the line being discussed. The symmetry operation here is the one where every point of the figure is flipped perpendicularly across the symmetry line and the object is symmetric if that flipping produced exactly the same set of points. (Said differently, if flipping the set of points through a line produced an exact replica of the original set of points, then the like determining the flip is a symmetry line.) One level of complication occurs if the straight line which is the subject of the symmetry question is an infinitely long straight line. In such a case one symmetry line still coincides with the actual line, but all lines that are perpendicular to the straight line will be lines of symmetry. Thus, an infinitely long straight line has no single point as its "middle" and has an infinitely many symmetry lines consisting of all possible lines perpendicular to the original line.
A parabola has a single focus point. There is a line running perpendicular to the axis of symmetry of the parabola called the directrix. A line running from the focus to a point on the parabola is going to have the same distance as from the point on the parabola to the closest point of the directrix. In theory you could look at a parabola as being an ellipse with one focus at infinity, but that really doesn't help any. ■

A single line cannot be perpendicular or parallel. These are attributes of two (or more) lines.
Lines of latitude are all parallel to each other, so do not converge. Lines of longitude do converge, at the north and the south poles.

One single line is never parallel or perpendicular. Those words tell you somethingabout the relationship between two lines.

The mountains converge into a single ridge.
There is no single characteristic for a place where things meet or converge. I would like to say that the place must be something physical, lines can converge on a page (or a screen), people can converge at a lunch table, rail lines converge in many places. However, that place isn't necessarily physical, you can have a meeting of minds, or ideas that converge in a single mind or in time.
Perpendicular lines are lines that intersect at a 90-degree angle. They can be visualized as forming a right angle or "L" shape. Parallel lines, on the other hand, are lines that never intersect and always stay the same distance apart. They can be visualized as two train tracks that never meet. Intersecting lines are lines that cross or meet at a single point. They do not have to be perpendicular or parallel, and their intersection forms an angle other than 90 degrees.
There's not a single cloud on the horizon. The expiration of the loan loomed like a dark cloud on their company's horizon.

Yes, perpendicular lines do intersect at a single point. Think of the line representing the x-axis, and the line representing the y-axis. These two lines are perpendicular, and they intersect at the Origin (a single point).
A single side cannot be perpendicular on its own. Two sides are perpendicular if they intersect at a 90 degree angle. There are many polygons, both regular and irregular, that can have perpendicular sides.
