If a straight line can be found on a graph, the graph can be aligned along this straight line, so that the two sides can completely overlap. Such a figure is called an axisymmetric figure, and this straight line is called an axis of symmetry. Careful observation shows that the plane is a standard axisymmetric object. Looking down, its wings, fuselage and tail are all symmetrical. Axial symmetry makes its flight more stable. If the plane is not axisymmetric, it will fly stagger. At that time, who wanted to fly? Looking closely, it is not difficult to find that many works of art are also axisymmetric. Take the simplest example: the bridge. It is the most common work of art in life. Take the bridges in Jinhua as examples: Tongji Bridge, Jinhongqiao, Shuanglong Bridge and Riverside Bridge. They are all axisymmetric. The ancient buildings in China are even more obvious. Ancient palaces were basically symmetrical. Another famous: the layout of Beijing. This is the most typical axisymmetric layout. It is symmetrical with the Forbidden City, Tiananmen Square, Monument to the People's Heroes and Qianmen as the central axis. The application of axial symmetry in art can make art look more beautiful. Axisymmetry is also a biological phenomenon: human ears, eyes and limbs all grow symmetrically. The axial symmetry of the ear makes the sound heard by children have a strong three-dimensional sense and can also determine the position of the sound source; The symmetry of eyes can make children see objects more accurately. It can be seen that our life is inseparable from axial symmetry. Mathematics is very close to students, which is reflected in all aspects of life. Students can't live without mathematics, which is everywhere. These are just two very common examples, and there are countless such examples. I believe that mathematics in life can bring more discoveries to people.
