What is direct and what is it?

As is known from geometry, "direct" means something that does not have bends and turns. The exact direction, even 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 ordinary communication of people among themselves.

What can be called direct

In order to understand the meaning of the word "direct", let us recall how we use it in ordinary speech. Then we will walk 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 value;
• 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 word combinations. For example, a direct direction is simply an indication of which way to move. A direct flight is a message that the traffic is from one point to another without stopping and changing the route.

How to distinguish a straight line, smooth from a curve

What is direct? In textbooks of geometry there is an explanation of this concept. A straight line is called the simplest geometric figure - a straight line that does not have a beginning or an end. The part of the line bounded by two points is called an interval. What is a straight line and a piece, we figured out.

Any feature can be curved or wavy, that is, a curve. If we successively join several independent "stretched" segments without observing one direction (in different directions), then a curve or a broken line will be obtained. When a line consists of arcs, bends and smooth turns, it is called curved, wavy. What is a line in geometry? If you go from the opposite, then this is every line that is not curve, 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, requiring frankness and truthfulness from all participants in this process. To do this, it is not necessary to know what a direct speech is, enough to talk about what is asked, or make specific proposals without concealment. During direct conversations, sometimes different secrets or hidden details of events are 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 necessary to remember the punctuation marks, what is direct speech, the author's words and other terms of the writers.

Spelling requires that the speaker's words be separated from the words of the author (the narrator) by a colon, quotes, commas and dashes. The allocation of words is influenced by the location of the words "hero" in the text, in the paragraph, in the line, and so on. That is, a direct speech is called verbatim one's words, included in the main plot of the story.

Winged bird and winged words

We found out what is direct in geometry and in literature, it's time to move further. By the way, in the previous sentence, one of the words was used in a figurative sense (move). That is, a second, not direct meaning, associated with the main name only was formed. There was a transfer of the name by action. It turns out that some of the words that we use have different meanings:

• Direct, or basic;
• Portable, or secondary.

What is the direct meaning of a word? The answer lies in the question itself. This is the name of a feature, an action, an object, or a phenomenon, which immediately gives rise to them, regardless of the 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 example:

• Move on the cart - move on the text;
• Gold nugget - golden hands;
• Chocolate candy - chocolate skin.

Which angle is a straight line

First of all, any angle is an independent geometric figure. If we connect three points not lying on the same line, then the point (or vertex) of this construction will be the angle. If several intersecting lines are drawn within any circle, several angles with pair values are formed at the point of intersection. The number of them will be equal to the number of lines drawn, multiplied by two.

All angles are measured in degrees, and the total value of the sum of all angles in the circle is 360 degrees. The corners are sharp and blunt, 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 perpendicular lines drawn through its center, four identical angles are formed. They are called straight lines and the meaning of each of them is 90 degrees.

How to build the right angle without a protractor

Sometimes in ordinary life it is necessary to apply or calculate the exact value of the angle. There are several simple 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 an accurate alignment of two adjacent sides, an angle of 45 degrees is formed.
• If you measure 10 cm on one side of a tetrad or any other sheet of paper, and on the other - 17.3 cm, 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 influence a particular response. One thing is unchanged: if you follow the steps in the right direction, take consistent steps and apply the acquired knowledge in practice, the result will necessarily be positive.

On parallel direct and fantasy worlds

What is direct? A point is the basic concept in geometry, it is something that does not have parts. An even, elongated line with no beginning and end, which has an infinite number of points, is straight.

To explain what parallel lines are, mathematicians use different definitions and comparisons. Here is one of the axioms: straight lines that nowhere and can never intersect are parallel. You can use one more method to determine the parallelism of lines. If from each point on one of the straight lines to be perpendicular (that is, at right angles) to the second equal segments, then these lines can not intersect and will be parallel.

What is parallel straight, is clear. And how does this relate to the fantastic worlds? The answer is quite simple, since in this case there is a transfer of concepts, which we discussed above. A possible reality that does not intersect, but is located next to ours, in the same space and time, and 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, the axiom is an assertion for which no proof is required. Below are some of these truths.

1. Any of the geometric or other shapes can be increased in accordance with proportions.

2. Two straight lines diverging in one direction will necessarily converge in the other.

3. If two straight lines are parallel to the third, then they are parallel to each other.

4. If two straight lines approach each other, they will someday cross.

5. If the lines approach each other, they can not disperse in the same direction without crossing.

6. Through any two points, you can draw a circle or a straight line.

7. The sum of the three angles is the same for all triangles, and it is equal to the power of two right angles.

8. A rectangle is a figure with four straight angles.

Imagine a world without geometry

Knowledge of what a straight line, segment, point, angle, is needed not only for students and students to get good grades. They are used by architects and designers, tailors and builders, geodesists and geologists, furniture makers and automakers, as well as a huge number of other professionals. Does someone 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, one might say, is the basis of architecture. The science of house building is also impossible without mathematical calculations and geometric concepts, like literature without words, points, commas, exclamation marks and direct speech.

What is a straight road? This is the 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.
