Before you start writing, observe the structure and proportion of Tian Zige. Tian Zige consists of four cells of equal size, with a cross line in the middle, which divides Tian Zige into two and a half cells on the left and right and two and a half cells on the upper and lower sides. By observing the proportion and symmetry of Tian Zige, we can grasp the layout and balance of writing.
It is very important to start and end this circle. Pay attention to the length and thickness of strokes and the connection with the previous stroke when starting a pen. Pay attention to the end of the stroke and the introduction of the next stroke when collecting the pen. In Tian Zige, observing the symmetry and proportion of up, down, left and right strokes can help us master the skills of starting and closing a pen.
You need to practice more if you want to write round words well. You can practice the writing of round characters repeatedly in Tian Zige, paying attention to the position, angle, spacing and cohesion of each stroke, as well as the balance and symmetry of the glyph structure. Through repeated practice, you can gradually master the skills and rules of writing round characters.
Application of circle:
1, the circle is a perfect geometric shape with high symmetry and invariance. Therefore, we will use circles on many occasions.
In mathematics, circle is an important concept. It can be expressed by a simple equation, that is, x? +y？ =r？ , where (x, y) is the point on the circle and r is the radius of the circle. Through this equation, we can easily calculate the basic quantities such as the circumference and area of a circle. In addition, the circle has some very interesting properties, such as the theorem of circumference angle and secant theorem, which are very useful in solving some mathematical problems.
2. In addition to mathematics, circles are also widely used in nature. For example, in biology, a cell is a perfect circle, which maintains the continuation of life through division and growth. In addition, circles also play an important role in physics.
For example, in mechanical engineering, the wheel is an important part. Its shape is round and it is easy to roll and rotate. The circle is also a very important element in architecture. For example, in ancient buildings, circular arches and arch windows were widely used, which made the buildings more stereoscopic and beautiful.
