Is the phrase two sides of a flat angle exactly in the same straight line true or false?

That's right. Analysis: When the two sides of the angle form a straight line, the angle surrounded by the two rays is a flat angle; From this, it can be seen that the two sides of the flat angle form a straight line, and it can be judged accordingly.

Solution: From the analysis, it can be seen that the two sides of the flat angle are correct in a straight line;

Comment: This question examines the definition of flat angles, so you should memorize them.

is wrong. An angle is defined as a graph consisting of two rays with a common point. Since it is "two rays with a common point", then the sentence "a flat angle is a straight line" is wrong because there are no points in a straight line. So this statement is wrong.

Must have a "point" (vertice), a "two rays" (an edge), and a composition of the shape. According to the characteristics of the straight line, it can be defined as follows: the straight line has no end point and can extend infinitely to both ends. Looking at the above definitions and characteristics, it is simply said that an angle is an angle, and a straight line is a straight line.

From high school geometry, I learned about the positional relationships between points, lines, and planes. An angle is the concept of a face, while a straight line is just a line.

concept. Therefore, even if the angle is flat, it is still a surface after all, and it cannot be said to be a line. A flat angle is simply the angle formed by the two corner edges of the corner.

It's just 180 degrees, and it's still a concept of faces. From the above statement, a flat angle is a straight line that is untenable. So I don't think a flat angle is a straight line.

In junior high school mathematics, is a flat angle a straight line? Such an understanding should be more vigilant, and it is recommended to collect it.

Two sides of a flat angle are paired in a straight line. Analysis: According to the meaning of the horn, it can be known:

The shape enclosed by two rays drawn from a vertex is called an angle, and the flat angle is equal to 180 degrees, so the two sides of the flat angle are on a straight ridge; Just judge it from this.

Brief introduction. A flat angle is an angle composed of two rays in opposite directions on the same straight line, and it is not possible to confuse a straight line with a ray, according to the definition of an angle: an angle is a graph composed of two rays with a common vertex.

That is, a flat angle is a ray made by a point in two opposite directions, and cannot be simply regarded as a straight line.

The two sides and vertices of the flat angle are on the same straight line, and the "special line" is seen from the "shape", so for the convenience of studying the problem, we sometimes have to look at the flat angle as a straight line. Taking a point in a straight line, this point divides the straight line into two limb rays with a common endpoint, and then we can think of the straight line as a flat angle. In a word:

For research purposes, straight lines and flat angles can be converted into each other.

Mistake. A flat angle is a straight line, which is false. A ray rotates around its endpoint, and when the beginning and end edges are in the same straight line and in opposite directions, the resulting angle is called a flat angle.

Flat angles are two rays, two rays of the same vertex, their endpoints are at the same vertex, and in opposite directions, they are on the same straight line. All the lines that make up the angle are rays. Not a line segment.

Because the corners have vertices. That is, if the line segment has an endpoint, it is a ray.

It should be right, the flat angle is 180 degrees, which is a straight line.

is wrong. Because a flat angle is an angle caused by two rays, not a straight line. This is a confusing question, and it is important to remember that any angle is caused by two rays.

A flat angle is a straight line, which is incorrect.

A flat angle is two rays in a straight line, and it is the angle formed when the two sides of the angle form a straight line. The flat angle is equivalent to 180°. Flat angles are only graphically the same as straight lines, but one is an angle, not a straight line.

When a ray rotates around its node, when the beginning and end edges are in the same straight line and the orientation is opposite, the resulting angle is called a flat angle. A flat angle is not a straight line, just two rays in a straight line.

It should be understood that all "angles" are produced by two rays with common endpoints, except for flat angles. It's just two rays that produce flat angles in a straight line.

The connection of flat angles with straight lines

Since the two sides of the flat angle and the vertex are on the same straight line, we sometimes have to look at the flat angle as a straight line in terms of "shape", so for the convenience of studying the problem, we sometimes have to treat the flat angle as a straight line.

Taking a point in a straight line, this point splits the line into two rays with a common endpoint, and we can think of the straight line as a flat angle. Bottom line: For research purposes, straight lines and flat angles can be converted into each other.

False, a flat angle is an angle that is made up of two rays drawn from a single point, whereas a straight line is made up of an infinite number of points.

1 flat angle = 180° + 360° k(k z) The flat angle is not a straight line, but two rays in a straight line. It should be understood like this: Any "angle" is formed by two rays with a common vertex, and flat angles are no exception.

Since a flat angle is an angle, it should conform to the definition of angle, that is, it is also composed of two rays, but the two rays are in opposite directions.

This statement is not true, a flat angle is an angle that is made up of two rays drawn from a point, while a straight line is made up of an infinite number of points.

A straight line is a flat angle? This statement is false because the angle is made up of 2 edges and a vertex. A "straight line" has no vertices and cannot be considered a flat angle.

False, a straight line can form a flat angle to be true. Because an infinitely extended straight line is just a straight line, there is no question of forming an angle.

From the analysis, it can be seen that the two sides of the flat angle are correct in a straight line;

So the answer is:
