The high line of a triangle can be used to represent the vertical distance between a vertex and its base, that is, the distance between a vertex and its corresponding base.
The height of triangle plays an important role in mathematics and geometry. It can help us better understand the properties of triangles, such as the relationship between area, bottom and height. The height line can also be used to prove some property theorems of triangles, such as the sum of three internal angles of a triangle is 180 degrees, and to judge some special triangles, such as right-angled triangles and isosceles triangles.
Triangular height line is also a common application to solve some practical problems. For example, when measuring the height of an object whose bottom cannot be directly reached, the height of the object can be calculated by measuring the shadow length of the object in the sun and the included angle between the high line and the bottom.
The application of triangle in life;
1. Bridge structure: Triangle is a very important structural form in bridge design. Because of its stability, triangles are widely used in bridge support and connection design. For example, in a suspension bridge, the triangular high line is used to support the main cable and the driveway where the car is installed. In addition, triangles are often used in the design of truss structures and bridge girders.
2. Architectural structure: Triangles are also widely used in architectural structures. For example, in building construction, triangular support structures are used in the design of roofs and floors of high-rise buildings. The stability of triangle is also often used in the frame structure and foundation design of buildings to ensure the safety and stability of buildings.
3. Mechanical parts: Triangles are also widely used in mechanical parts. For example, triangular connecting rods, pistons and crankshafts are common mechanical parts. The characteristics of triangle, such as stability, wear resistance and strength, are applied to the design of these parts to improve the efficiency and performance of mechanical equipment.
