The origin of the boxer rebellion:

The origin of boxers can be traced back to the geometry of ancient Greece. In geometry, a right angle is a basic right angle, which refers to the angle formed when two rays are on the same straight line and in opposite directions. The degree of a right angle is 180 degrees, which is widely used in mathematics and physics.

Mathematicians in ancient Greece established the mathematical concept of right angle by studying the definitions and properties of straight lines, rays and angles. The definition and properties of right angles have been widely used in Euclidean geometry, which is one of the foundations of ancient western mathematics.

With the passage of time, the definition and properties of right angles have been widely used in other disciplines, including physics, engineering, astronomy and so on. In modern mathematics and physics, right angle is still an important concept and is widely used.

In the study of ancient Greek mathematicians, the definition of right angle has not changed. The concept of a flat angle is a basic flat angle, which refers to the angle formed when two rays are on the same straight line and in opposite directions. This definition has remained unchanged in the research of ancient Greek mathematicians, and has been widely used in mathematics, physics and other fields.

Application of flat angle:

1. Architectural design: When designing the plane layout of the house, you can use right angles to determine the layout and size of the room. For example, we usually design the layout of the living room at right angles, which is more comfortable and practical. In addition, right angles are also widely used in the structural design of buildings. For example, when designing the supporting structure of bridges or buildings, it is necessary to consider the straight angle to ensure the stability and firmness of the structure.

2. Geographical survey: Geographers use a right angle to measure the shape and position of natural geographical elements such as mountains, rivers and lakes. By measuring the angles between geographical elements, the distance and direction between them can be determined. Boxes are also used to determine the orientation relationship between different parts of the earth's surface. For example, the calculation of latitude and longitude is based on the principle of box.

3. Aerospace: In the manufacture of missiles and satellites, engineers use right angles to determine the direction of missiles or satellites to ensure that they can navigate correctly and reach their destinations.

4. Astronomy: In the field of astronomy, the straight angle is the basis for calculating the positions of constellations, planets and stars. Because the flat angle is a fixed angle, it can help astronomers determine the position of planets or constellations in the sky.

5. Trigonometric function: The right angle is one of the simplest angles in trigonometric function, and its sine, cosine and tangent are all zero. This means that if you want to find an angle whose sine, cosine or tangent is equal to zero, then the angle must be a right angle. Therefore, the right angle is one of the simplest angles in trigonometric function.

Generally speaking, boxers are widely used in mathematics and real life. In mathematics, as one of the simplest angles in a triangle, it is often used to calculate the area and solve the triangle problem. In real life, boxers play an important role in architecture, furniture design, aviation and astronomy.
