As is known from geometry, “direct” means something that does not have twists and turns. The exact direction, flat highway, frank conversation is also called the same word. This concept, of course, is used in other areas of life, including in literature and in the usual communication of people among themselves.
What can be called direct
In order to understand the meaning of the word “direct”, we recall how we use it in ordinary speech. Then go through each item separately. So, a simple enumeration can be called the following phrases with this word:
- straight road;
- direct conversation;
- right angle;
- direct dependency;
- straight line;
- direct meaning;
- direct speech;
- direct flight;
- direct direction;
- and so on.
In each case, the explanation of the meaning will be completely different, despite the use of the same word in all phrases. For example, a direct direction is simply an indication of which direction you want to move. A direct flight is a message that the movement will take place from one point to another without stops and route changes.
How to distinguish a straight, smooth from a curve
What is a straight line? In the textbooks of geometry there is an explanation of this concept. The straight line is called the simplest geometric figure - an even line with no beginning or end. The part of the line bounded by two points is called a segment. What is a line and a segment, we figured out.
Any feature may be curved or wavy, that is, a curve. If several independent “stretched” segments are connected in series without following one direction (in different directions), a curve or a broken line is obtained. When a line consists of arcs, bends and smooth turns, it is called curved, wavy. What is a straight line in geometry? If we go from the opposite, then this is every line that is not curved, wavy, broken or curved.
What is common between direct conversation and direct speech
Judging by the explanation of authoritative dictionaries, direct conversation is a serious conversation, requiring frankness and truthfulness from all participants in this process. For this, it is not necessary to know what direct speech is, it is enough to talk about what is being asked, or to make specific proposals without hiding. During direct conversations, various secrets or hidden details of events are sometimes clarified. Most often, such conversations occur between close people, friends or relatives.
But in order to accurately convey or record this conversation on paper, it is already necessary to recall the punctuation marks, what is direct speech, the words of the author and other terms of writers.
Spelling requires that the speaker’s words be separated from the author’s (narrator’s) words by a colon, quotation marks, commas, and dashes. Speech highlighting is affected by the location of the words “hero” in the text, in the paragraph, in the line, and so on. That is, direct speech refers to someone’s literally reproduced words included in the main plot of the story.
Winged bird and winged words
We found out what a straight line is in geometry and in literature, it is time to move on. By the way, in the previous sentence, one of the words was used figuratively (to move). That is, a second, not direct meaning was formed, associated with the main only name. The name transfer by action has occurred. It turns out that some of the words we use have different meanings:
- direct or basic;
- figurative, or secondary.
What is the direct meaning of the word? The answer lies in the question itself. This is the name of a sign, action, object or phenomenon that immediately brings about them, regardless of context. The ambiguity of the concept is formed by transferring the name to something else, not connected in any way with the basic, direct meaning of the word. For instance:
- move on a cart - move along the text;
- gold nugget - golden hands;
- chocolate candy - chocolate skin.
Which angle is right
First of all, any angle is an independent geometric figure. If you connect three points that are not on the same line, the point (or vertex) of this structure will be the angle. If several lines intersecting each other are drawn inside any circle, then several angles with paired values ​​are formed at the point of their intersection. Their number will be equal to the number of drawn lines, multiplied by two.
All angles are measured in degrees, and the total value of the sum of all angles in a circle is 360 degrees. Angles are sharp and obtuse, straight and unfolded, adjacent, vertical and additional.
What is a right angle? How to get it, where to find it? Inside the circle, divided by two lines perpendicular to each other drawn through its center, four identical angles are formed. They are called straight and the value of each of them is 90 degrees.
How to build the right angle without a protractor
Sometimes in everyday life it is necessary to apply or calculate the exact value of the angle. There are several easy ways to do this.
- If you take a sheet from any notebook or book, then all its angles are equal to 90 degrees.
- When folding such a sheet with a neat combination of two adjacent sides, an angle of 45 degrees is formed.
- If you measure 10 cm on one side of a notebook or any other sheet of paper, and 17.3 cm on the other, and then connect these points with a line, you can get a template whose angles are 90, 60 and 30 degrees.
What is the direct dependence of the result on actions? A variety of factors can affect a specific response. One thing is invariable: if you perform actions in the right direction, take sequential steps and apply the acquired knowledge in practice, then the result will be necessarily positive.
On parallel straight and fantastic worlds
What is a straight line? A point is a basic concept in
geometry, it is something that has no parts. A flat, elongated line with no beginning or end, which has an infinite number of points, is a straight line.
To explain what parallel lines are, mathematicians use different definitions and comparisons. Here is one of the axioms: the lines are straight, which can never intersect anywhere, are parallel. You can use another method to determine the parallelism of the lines. If equal segments are drawn from each point on one of the lines perpendicularly (that is, at a right angle) to the second, then these lines will not be able to intersect and will be parallel.
What are parallel lines, clear. And how does this relate to the fantasy worlds? The answer is quite simple, since in this case there is a transfer of concepts, which were discussed above. A possible reality, not intersecting, but located next to ours, in the same space and time, is a parallel world. It is believed to be true that the processes that take place there in no way affect our world.
Several well-known axioms
In the mathematical world, an axiom is a statement for which evidence is not required. The following are some of these truths.
Any of the geometric or other shapes can be increased in proportion.
Two straight lines diverging in one direction will certainly converge in the other.
If two lines are parallel to the third, then they are parallel to each other.
If two straight lines converge, they will ever intersect.
If the lines approach each other, they will not be able to disperse in the same direction without crossing.
Through any two points, you can draw a circle or a straight line.
The sum of the three angles is the same for all triangles, and it is equal to the sum of two right angles.
A rectangle is a figure with four right angles.
Imagine a world without geometry
Knowledge of what a straight line, a segment, a point, an angle is needed not only for schoolchildren and students to obtain good grades. They are used by architects and designers, tailors and builders, surveyors and geologists, furniture makers and car makers, as well as a huge number of other specialists. Does anyone want to wear an ugly dress or live in a house with crooked, falling walls?
What is a right angle? Lines, segments, planes, points and angles - this can be said to be the basis of architecture. The science of homebuilding is just as impossible without mathematical calculations and geometric concepts as literature without words, dots, commas, exclamation points, and direct speech.
What is a straight road? This is a path leading from one point to another (or from one concept to another, from ignorance to erudition, for example), with possible stops in time, but without deviations from the chosen route.
