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!
horizon is STUPID
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
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
Yes, it is. Think of the horizon. A horizontal line is parallel to the horizon.
The horizon, possibly.
A horizontal line is a line that is parallel to the horizon.
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.
Not sure about the horizon number line but the horizontal line is sometimes called the x-axis.
What it means is horizontal line is like the horizon it goes across
The horizon line is where the earth meets the sky. In a photograph, the horizon line should be horizontal (flat) or the picture will looked tilted.
It's a line segment that's parallel to the horizon.
The horizon runs horizontal. Perpendicular to that is VERTICAL.
