Horizontal.
a line lol not saying real ancer
parallel isn't a case of direction, it just means two lines that will never bisect (check out the "L"s in parallel). There is the 49th degree North parallel but it is really just a line of latitude. also, just for clarification, horizontal is going across (just think of the horizon) and vertical is going up. :)
The answer will depend on whether you mean parallel edges or parallel faces.
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 line parallel to the horizon would be level and run parallel to the Earth's surface without intersecting it. This is commonly seen in landscapes where structures or objects appear parallel to the horizon.
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
bounded (circle). In Greek 'horizon' was originally used to mean "bounding earth" with the property that it was parallel with the earth. Later, the Earth was normally thought to be flat: thus, 'horizontal' came to mean parallel to the earth.
A point on the horizon where parallel lines appear to meet is called the vanishing point.
Horizontal.
Lines of latitude are all parallel to each other, and are parallel to the horizon on many printed maps.
Yes, it is. Think of the horizon. A horizontal line is parallel to the horizon.
A horizontal line is a line that is parallel to the horizon.
because they are parallel to the plane of the horizon
Parallel lines never intersect and always remain equal distance from each other.
It's a line segment that's parallel to the horizon.
The "horizon" is the furthest you can see. "On the horizon" therfore refers to an object which is just in sight.
