The opposite of vertical, something horizontal is arranged sideways, like a person lying down. When you sleep (unless you’re a horse), your body is horizontal: horizontal things are parallel to the ground or running in the same direction as the horizon. If you stack books horizontally, then they’re on their side.

Which line is horizontal?

A horizontal line is a straight line that is drawn from left to right or right to left and it is parallel to the x-axis in the coordinate plane. In other words, a straight line that has an intercept only on the y-axis, not on the x-axis is called a horizontal line.

What is this word horizontally?

adjective. at right angles to the vertical; parallel to level ground. flat or level: a horizontal position. being in a prone or supine position; recumbent: His bad back has kept him horizontal for a week.

What is an example of a horizontal line?

Examples. Look at a wall, and look down to where that wall meets the floor. That intersection is a horizontal line. Other examples of horizontal lines we may see every day are the following: the line separating the sky from the land across a clear plain or the line separating the sky from the water at the beach.

Is horizontal left to right?

Anything parallel to the horizon is called horizontal. So, the horizontal line is one that runs across from left to right. Use of horizontal and vertical in Mathematics. We add and subtract horizontally and vertically.

Is horizontal across?

In geometry, a horizontal line is one which runs from left to right across the page. It comes from the word ‘horizon’, in the sense that horizontal lines are parallel to the horizon. Its cousin is the vertical line which runs up and down the page. A vertical line is perpendicular to a horizontal line.

Is horizontal a direction?

Conversely, a direction or plane is said to be horizontal if it is perpendicular to the vertical direction. In general, something that is vertical can be drawn from up to down (or down to up), such as the y-axis in the Cartesian coordinate system.

Which way is horizontal picture?

Horizontal photographs are photographs that are wider than they are tall. Vertical photographs are photographs that are taller than they are wide. Cameras are designed to take one type of photograph — horizontal.

Which is the best definition of the word horizontal?

English Language Learners Definition of horizontal : positioned from side to side rather than up and down : parallel to the ground : lying flat or level : parallel to the horizon : something (as a line or plane) that is parallel to the horizon

What’s the difference between horizontal and vertical lines?

Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal, anything that makes a 90-degree angle (right angle) with the horizontal or the horizon is called vertical. So, the horizontal line is one that runs across from left to right. Use of horizontal and vertical in Mathematics

Which is the opposite of horizontal In geometry?

Horizontal is the opposite of vertical. In geometry, we use the words vertical and horizontal for standing and sleeping respectively. The line at which the earth’s surface and the sky appear to meet is called the horizon. Anything parallel to the horizon is called horizontal. As vertical is the opposite of horizontal.

What is the medical definition of horizontal transfer?

3 medical : relating to or being transmission (as of a disease) by physical contact or proximity in contrast with inheritance Genes are normally inherited from parents, but they can also be inserted into a genome by viruses, plasmids, and other foreign agents—a phenomenon called horizontal transfer.— Stephan Reebs — compare vertical sense 4.
