Volkswagen, Mercedes-Benz, Audi, Toyota, Honda, Mazda, Chery, Citroen, China FAW, Bentley, Great Wall, Lincoln, Mitsubishi, Changan, Dayu, Crown, etc., are all axisymmetric graphics.

1. Volkswagen: The German word volkswagenwerk for Volkswagen means a car used by the public. The vw in the logo is the first letter of the full name. The logo consists of three "v"s made with the middle and index fingers, which means that Volkswagen and its products must win-win-win.

2. Mercedes-Benz: In June 1909, Daimler applied to register the "three-pointed star" as the logo of the car, symbolizing the mechanization and integration of land, water and air. In 1916, a circle was added around it, with four small stars inlaid above the circle and the words "Mercedes" below. "Mercedes" means happiness, which means that cars produced by Daimler will bring happiness to car owners

3. Audi: The logo of Audi cars is four rings, representing mergers the previous four companies. These companies used to be [Audi S4] Audi S4 manufacturers of bicycles, motorcycles and passenger cars. Since the company was originally formed by the merger of four companies, each ring is a symbol of one of the companies. ?

4. Toyota: The Toyota logo is the three oval logo of Toyota, which has been used since the early 1990s. The large oval in the logo represents the earth, and the two ovals in the middle are vertically combined to form a T, which represents Toyota. It symbolizes that Toyota is based on the future, its confidence and ambition for the future. It also symbolizes that Toyota is based on customers and guarantees customers. It symbolizes that the hearts of users and the hearts of automobile manufacturers are connected together, with a sense of mutual trust. At the same time, it symbolizes Toyota's superb technology and innovation potential.

5. Honda: "H" is the graphic trademark of "Honda" cars and "Honda" motorcycles. It is the first capital letter of "Honda" in Japanese pinyin "HONDA". The letters in the Honda car trademark "HM" is the abbreviation of "HONDAMOTOR". There are eagle wings on these two letters, which symbolizes "Leaping Honda's technology and Honda's promising future"

6. Mitsubishi Group. ) is a loose entity formed by the original company partners after the disintegration of the Mitsubishi Zaibatsu. Mitsu in the name Mitsubishi means "three", and bishi means "water chestnut"

7. Lincoln. The sedan is a luxury car brand owned by the famous American automobile company Ford. It was founded in 1917 by Henry Leland. Its brand name is named after U.S. President Abraham Lincoln.

Since 1939. Since U.S. President Franklin Roosevelt in 1998, Lincoln has been selected as the presidential car by the White House due to its outstanding performance, elegant style and unparalleled comfort. Its most "famous" car is the Lincoln brand used by President Kennedy. Famous products include: MKC, MKZ, "Continental", "Mark VIII", "TownCar" and "Navigator", etc. Most of the Lincoln cars used in China are "Town" cars. series.

Extended information:

If a plane figure is folded along a straight line, and the parts on both sides of the straight line can overlap each other, then the figure is called an axially symmetric figure (a figure has reflectional symmetry) , this straight line is called the axis of symmetry.

Note: As long as the diagonally placed figure can be folded along a straight line and the figures on both sides of the straight line can overlap each other, it is an axially symmetrical figure. Draw a line in the middle of an axially symmetrical figure. That line is called the axis of symmetry.

Axisymmetric figure (axial symmetric figure), a mathematical term, is defined as a figure that is folded along a straight line in a plane, and the parts on both sides of the straight line can completely overlap.

The straight line is called the axis of symmetry, and the axis of symmetry is represented by a dotted line; at this time, we also say that the figure is symmetrical about this straight line. Such as circles, squares, isosceles triangles, equilateral triangles, isosceles trapezoids, etc.

Properties:

1. The axis of symmetry is a straight line.

2. In an axially symmetrical figure, the distance from corresponding points on both sides of the symmetry axis to both sides of the symmetry axis is equal.

3. In an axially symmetrical figure, fold it in half along the axis of symmetry, so that the left and right sides completely overlap.

4. If two figures are symmetrical about a straight line, then this straight line is the axis of symmetry and the axis of symmetry perpendicularly bisects the line segment connected to the symmetry point.

5. Graphic symmetry.

The role of axisymmetric design in daily life

1. For the sake of beauty. For example, in Tiananmen Square, symmetry makes it look beautiful.

2. Maintain balance. For example, the wings of an airplane.

3. Special work needs. Such as five-pointed stars and paper cuts.

To distinguish between these two concepts, attention should be paid to: an axially symmetrical figure must be folded along a certain straight line and the parts on both sides of the straight line overlap each other. The key points are: first, folding along a certain straight line, and second, the two parts overlap each other. ; A centrally symmetrical figure is a figure that rotates 180° around a certain point and then coincides with the original figure. The key is to focus on two points: one is to rotate around a certain point, and the other is to coincide with the original figure.

The actual difference is that the axially symmetrical figures should be folded like origami. The axially symmetrical figures that can overlap are the axially symmetrical figures; the centrally symmetrical figures only need to turn the figures upside down and observe whether there is any change. The unchanged ones are the centrally symmetrical figures. Common graphics in primary school textbooks are now classified as follows: Graphics that are both axially symmetrical and centrally symmetrical include: rectangle, square, circle, rhombus, etc.

Only axis-symmetrical figures include angles, five-pointed stars, isosceles triangles, equilateral triangles, isosceles trapezoids, etc.

The only centrally symmetrical figures are: parallelogram.

Graphics that are neither axially symmetrical nor centrally symmetrical include: scalene triangles, non-isosceles trapezoids, etc.

A figure that is both axially symmetrical and centrally symmetrical must have two or more axes of symmetry.
