1. Determine the theme and knowledge points: Make it clear that the theme of this chapter is "geometric figures", and then list the main knowledge points of this chapter, such as line segments related to triangles, angles related to triangles, polygons and the sum of their internal angles.
2. Sort out the sub-knowledge points and logical relations: list the corresponding sub-knowledge points under each main knowledge point, and structure the information with elements such as graphics and colors to make each node clear. At the same time, pay attention to sort out the logical relationship between knowledge points, such as the nature and judgment of parallel lines and congruent triangles's judgment.
3. Check and improve the mind map: check the logic and integrity of the mind map to ensure that all key knowledge points are included. If necessary, you can adjust and improve the mind map to make it more in line with your own learning needs.
Information related to mathematics
1. Origin and development of mathematics: Mathematics originated from human observation and thinking of natural and social phenomena. From ancient Egypt, Babylon to ancient Greece, and then to modern times, mathematics has continuously developed and evolved, forming a rich and diverse theoretical system and applied technology. China's ancient nine-chapter arithmetic is a well-known mathematical classic.
2. Application of mathematics: Mathematics is widely used in science, engineering, economy and other fields. For example, the theories of mechanics and electromagnetism in physics are all based on mathematics; The algorithm design and data structure in computer science are also inseparable from the support of mathematics; The optimization problem and probability theory in economics also need to be solved by mathematical methods.
3. Mathematics education: In China, mathematics education is one of the compulsory courses from primary school to high school. Students need to learn basic knowledge such as arithmetic operation, algebra and geometry, and gradually deepen advanced contents such as function and calculus. In addition, there are many excellent mathematicians and research institutions in China, such as China, etc. They have made outstanding contributions in the field of mathematics.
