Explain in detail:
Since all four sides of a square are equal, as long as the length of one side is known, the circumference of the whole square can be calculated. For example, if the side of a square is 5 cm, its circumference will be equal to 5 cm times 4, that is, 20 cm.
The concept of perimeter:
The perimeter refers to the length of a closed curve, while the perimeter of a square refers to the total length of its four sides. Because all four sides of a square are equal, the formula of perimeter is very simple. You can get the perimeter value by multiplying the side length by 4. This formula applies to squares of any size.
Introduction to the square:
Square is a geometric shape with special symmetry. It is a quadrilateral, each angle is 90 degrees, and its four sides are equal in length. Compared with other shapes, squares are characterized by higher symmetry and stability. Because all parties are equal,
The application of square:
1, architectural design
Square is widely used in architectural design, such as square room and architectural layout. Square structure can provide a sense of stability and balance, making the building more stable in structure.
2. Urban planning
In urban planning, grid is often used in road layout and land division. This planning method is simple and efficient, which is convenient for navigation and traffic flow, as well as land distribution and management.
3. Board game
Chess, checkers and other board games all use square grids. This layout ensures that each chess piece has a clear position on the chessboard, which is convenient for calculation and movement.
4, icon and interface design
Square icons are very common in the design of applications, websites and user interfaces. They can be used to represent different functions, menu options, buttons and so on, giving users clear visual guidance.
5. Art and decoration
Square can be used as the basic shape of artworks and decorations, and can be used in painting, photography, murals and other fields. The symmetry and balance of the square give the work a sense of beauty and stability.
6. Mathematics and Geometry
Square is one of the basic geometric shapes in mathematics, which is used for teaching, researching and proving various geometric theorems. It is the basis of other shapes, for example, a cube consists of six squares.
7. Assembly design
Square containers are widely used in commodity packaging design because they are easy to stack, transport and display. The boxes and wrapping paper of many products are square to provide good storage and display effects.
