What way does a horizontal line go?
A horizontal line is one which runs left-to-right across the page. 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.
Which way is horizontal and which way is vertical?
Horizontal vs Vertical. Horizontal refers to physical space from left to right, or space that is parallel to the horizon. Vertical refers to space from up to down that is perpendicular to the horizon. For example, a person laying on their back on the beach is in a horizontal position and a person standing on a beach is in a vertical position.
What direction does a vertical line go?

Is vertical a direction?
The terms vertical and horizontal often describe directions: a vertical line goes up and down, and a horizontal line goes across. You can remember which direction is vertical by the letter, "v," which points down.

Which line is horizontal?
A horizontal line is a straight line that goes from left to right or right to left. In coordinate geometry, a line is said to be horizontal if two points on the line have the same Y- coordinate points. It comes from the term “horizon”. It means that the horizontal lines are always parallel to the horizon or the x-axis.
What means horizontal position?
In this context, a horizontal position is the location of a point relative to two axes: the equator and the prime meridian on the globe, or x and y axes in a plane coordinate system. Control points tie coordinate systems to actual locations on the ground; they are the physical manifestations of horizontal datums.

What is horizontal on a graph?
In more simple terms, a horizontal line on any chart is where the y-axis values are equal. If it has been drawn to show a series of highs in the data, a data point moving above the horizontal line would indicate a rise in the y-axis value over recent values in the data sample.

Is a man lying flat on the floor the same as a man lying horizontally on the floor?
A man lying flat on the floor is the same as a man lying horizontally on the floor. 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 ...

What is horizontal direction drilling?
What Is Horizontal Directional Drilling? Horizontal Directional Drilling or HDD, is a steerable trenchless method of installing underground pipe, conduit, or cable in a shallow arc along a prescribed bore path by using a surface-launched drilling rig, with minimal impact on the surrounding area.
What is directional drilling?
Directional Drilling is used when trenching or excavating is not practical. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings. Pipe can be made of materials such as PVC, polyethylene, polypropylene, ductile iron, and steel as long as it can be pulled through the drilled hole.
How does a drill head work?
A drill head can enter the soil from ground level, be manipulated to follow a planned bore path and return to the surface at a distance from the entry point. A reamer and the product to be installed are pulled back through the bore path to the initial entry point.
How high should a buried structure be?
All buried structures within 10 to 25-feet (depending on mini or maxi HDD application) of the route, should be located to avoid cross boring.
What is HDD drilling?
Horizontal directional drilling (H DD) is becoming widely accepted in the construction industry as a convenient way to get a pipeline drilling job done with minimum disruption to everyday life. It has gained interest mainly due to the fact that HDD projects do not involve digging up entire stretches of roads, though the entry ...
What is directional drilling?
Directional drilling is a broad term used to describe any boring that doesn’t go in a straight line vertically down. In fact, even in a vertical well, it might be necessary to deviate to avoid a geological formation or a previous stuck pipe, then return to the original path. In this instance, the driller uses sidetracking techniques.
How long has directional drilling been around?
Directional drilling techniques have been employed for almost 100 years now. Over the past few decades, technological improvements have meant that angles, turns and underground distances covered are amazing feats of engineering.
How do the engineers know where the end of the drill is?
It’s not possible to see hundreds of metres underground, in fact, the drillers and engineers rely entirely on technology to ‘see’ where they are going. A directional driller has a guide that has been created by the engineers and geologists. Every 10-150 metres, (with 30-40 being typical), survey data is sent back to make sure that the original ‘blue line’ well path is being followed.
Can horizontal drilling avoid salt domes?
It’s common to find deposits below salt domes or fault planes, where the driller faces increased technical risk. Horizontal drilling can avoid salt domes, and reduce pressure on equipment near fault lines.
Is drilling a well directional?
In conventional drilling for oil and gas, the drill bit, drillstring, pipe and casing all go down in a straight line. If a driller aims away from the 180-degrees down, that’s technically directional drilling. Nowadays, however, it’s more likely that there’ll be a series of one or more carefully planned directional changes along the wellbore.
Overview
In astronomy, geography, and related sciences and contexts, a direction or plane passing by a given point is said to be vertical if it contains the local gravity direction at that point. 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.
Historical definition
The word horizontal is derived from the Latin horizon, which derives from the Greek ὁρῐ́ζων, meaning 'separating' or 'marking a boundary'. The word vertical is derived from the late Latin verticalis, which is from the same root as vertex, meaning 'highest point' or more literally the 'turning point' such as in a whirlpool.
Girard Desargues defined the vertical to be perpendicular to the horizon in his 1636 book Perspec…
Geophysical definition
In physics, engineering and construction, the direction designated as vertical is usually that along which a plumb-bob hangs. Alternatively, a spirit level that exploits the buoyancy of an air bubble and its tendency to go vertically upwards may be used to test for horizontality. A water level device may also be used to establish horizontality.
Mathematical definition
In the context of a 1-dimensional orthogonal Cartesian coordinate system on a Euclidean plane, to say that a line is horizontal or vertical, an initial designation has to be made. One can start off by designating the vertical direction, usually labelled the Y direction. The horizontal direction, usually labelled the X direction, is then automatically determined. Or, one can do it the other way around, i.e., …
Discussion
Although the word horizontal is commonly used in daily life and language (see below), it is subject to many misconceptions.
• The concept of horizontality only makes sense in the context of a clearly measurable gravity field, i.e., in the 'neighborhood' of a planet, star, etc. When the gravity field becomes very weak (the masses are too small or too distant fr…
