As we know from geometry, "straight" means something that does not have bends and turns. The exact direction, a smooth highway, a frank conversation is also called the same word. This concept, of course, is also used in other areas of life, including literature and in ordinary communication between people.
What can be called direct
In order to understand the meaning of the word "straight", let's remember how we use it in ordinary speech. Then we will go through each item separately. So, the following phrases with the given word can be called a simple enumeration:
- straight road;
- straight talk;
- right angle;
- direct dependence;
- 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, the forward direction is simply an indication of which direction to move. And a direct flight is a message that the movement will take place from one point to another withoutstops and route changes.
How to distinguish straight, straight from crooked
What is a straight line? In geometry textbooks there is an explanation of this concept. A straight line is the simplest geometric figure - a straight line that has neither beginning nor end. The part of a straight line bounded by two points is called a segment. What is a straight line and a segment, we figured it out.
Any feature can be curved or wavy, that is, a curve. If you successively connect several independent "stretched" segments without observing the same direction (in different directions), you get a curved or broken line. When the line consists of arcs, bends and smooth turns, it is called curved, wavy. What is a straight line in geometry? Reversely, it is every line that is not crooked, wavy, broken, or curved.
What is common between direct conversation and direct speech
Judging by the explanation of authoritative dictionaries, a direct conversation is a serious conversation that requires frankness and truthfulness from all participants in this process. To do this, it is not necessary to know what direct speech is, it is enough to talk about what is being asked without hiding, or to make specific proposals. During direct conversations, various secrets or hidden details of events are sometimes revealed. Most often, such conversations take place between close people, friends or relatives.
But in order to accurately convey or write down this conversation on paper, it is already necessary to rememberpunctuation 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 colons, quotation marks, commas and dashes. Speech selection is influenced by the location of the words "hero" in the text, in a paragraph, in a line, and so on. That is, direct speech is called literally reproduced someone's words included in the main plot of the story.
Winged bird and winged words
We figured out what a line is in geometry and in literature, it's 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, connected with the main name only. There was a transfer of the name by action. It turns out that some of the words we use have different meanings:
- direct, or basic;
- portable or secondary.
What is the direct meaning of the word? The answer lies in the question itself. This is the name of a feature, action, object or phenomenon, which immediately causes an idea about them, regardless of the context. The ambiguity of a concept is formed by transferring the name to something else, in no way connected with the main, direct meaning of the word. For example:
- move on the cart - move through the text;
- gold nugget - golden hands;
- chocolate candy - chocolate skin.
Which angle is right
Beforejust any angle is an independent geometric figure. If you connect three points that do not lie on the same straight line, then the tip (or vertex) of this construction will be the angle. If you draw several intersecting lines inside any circle, then at the point of their intersection several angles with paired values are formed. The number of them will be equal to the number of drawn lines, multiplied by two.
All angles are measured in degrees, and the full value of the sum of all angles in a circle is 360 degrees. Angles are sharp and obtuse, straight and developed, 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 lines and the value of each of them is 90 degrees.
How to line up the desired angle without a protractor
Sometimes in everyday life it is necessary to apply or calculate the exact value of an 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? For a specific answermay be affected by a variety of factors. One thing is constant: if you take actions in the right direction, take consistent steps and apply the knowledge gained in practice, then the result will be positive.
About parallel lines and fantasy worlds
What is a straight line? A point is a basic concept in geometry, it is something that has no parts. A smooth, elongated line without a 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: straight lines that can never and nowhere intersect are parallel. You can use another method to determine the parallelism of the lines. If from each point on one of the lines to build perpendicular (that is, at right angles) to the second equal segments, then these lines will not be able to intersect and will be parallel.
What are parallel lines, clearly. How does this relate to fantasy worlds? The answer is quite simple, since in this case there is a transfer of the concepts discussed above. A possible reality that does not intersect, but is located next to ours, in the same space and time, is a parallel world. It is considered true that the processes that take place there do not affect our world in any way.
Several well-known axioms
In the mathematical world, an axiom is a statement that does not require proof. Belowsome of these truths are given.
- Any of the geometric or other shapes can be enlarged in proportion.
- Two straight lines diverging in one direction will necessarily converge in the other.
- If two lines are parallel to a third, then they are parallel to each other.
- If two straight lines come close, they will eventually cross.
- If the lines are approaching, they will not be able to diverge in the same direction without crossing.
- A circle or a straight line can be drawn through any two points.
- The sum of 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 about what a line, segment, point, angle is, is needed not only for schoolchildren and students to get 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 professionals. Who wants 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 are, one might say, the basis of architecture. The science of building construction is just as impossible without mathematical calculations and geometric concepts, as well as literature without words, periods, commas, exclamation marks and direct speech.
What is a straight road? It 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 deviating from the chosen route.
