The concept of a "horizontal line" or "horizontal" existed before the concept of a "horizon." The term "horizontal" is used in geometry and mathematics to describe a line or plane that is parallel to the horizon or perpendicular to the vertical direction (i.e., it runs flat from left to right). The word "horizontal" has been used in this geometric sense for centuries.
On the other hand, the term "horizon" primarily refers to the apparent boundary between the Earth and the sky as seen from a specific point. The concept of the horizon has been part of human observation and language for much longer than precise geometric terminology. It's a fundamental aspect of how we perceive the world, particularly the natural world.
So, to summarize, the concept of a "horizontal line" came first in the context of mathematics and geometry, while the concept of the "horizon" has been a fundamental part of human observation and understanding of the Earth's curvature for a much longer time.

What is collimation error?
error in alignment between the optical axis of a telescope & the declination. it is line set out by the optical axis of the instrument ( level). so it is just an imaginary line that describes the ray of light that allows us to read different values from the leveling staff. this term arose from the fact that in differential leveling in surveying we must construct horizontal line of sight, but due to collimation error the collimation line (i.e. line of sight) will not be 100% horizontal (by horizontal we mean tangent the level surface at the instrument position), instead it will be slightly deviated. so what we are looking to achieve when we eliminate the collimation error (using the 2 peg test) is a horizontal line of collimation.
Roof with two slopes and gable at both ends?
If the gable is formed by the two slopes and a horizontal line, it is called a gable roof.

What is the line for autocad?
Line, is a basic command as a single line that can form into an object. However, this command can not be formed into three dimensions. To shape it needs to change the structure of the line to polyline
What is mean by center line plan?

What came first the word Horizon or the name given to a horizontal line?
horizon is STUPID
What came first the word horizon or the name horizontal line?
horizon came first because the horizon runs in a line along the sky, which really is an optical illusion to us, so people in ancient times would think the horizon was a straight line sideways hence the word horizontal
What came horizon or a horizontal line?
I think horizon came first because people from long ago named the horizon horizon and, from there, we developed the word horizontal. By the way, horizontal means running from side to side. Hope it helped!
Is a vertical line parallel to the horizon?
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
Is a horizontal line left to right?
Yes, it is. Think of the horizon. A horizontal line is parallel to the horizon.
What is the name of the of the horizontal line?
The horizon, possibly.
What is the definition of a horizonal line?
A horizontal line is a line that is parallel to the horizon.
The horizon number line is called the?
Not sure about the horizon number line but the horizontal line is sometimes called the x-axis.
What does horizontal mean in the math?
What it means is horizontal line is like the horizon it goes across
What is a horizontal line segment?
It's a line segment that's parallel to the horizon.
When using two point perspective in a composition the vanishing points are located?
The two vanishing points are placed apart on the same horizon line (horizontal eye line of viewer). The horizon is the first line to be drawn.
A line that runs perpendicular to the plane or the horizon what is it called?
The horizon runs horizontal. Perpendicular to that is VERTICAL.
