Practical application types of similar triangles.

The practical application types of similar triangles are as follows:

1. Measuring height:

In the nature of similar triangles, we know that the corresponding edges of similar triangles are proportional. So we can use this property to measure the height that cannot be measured directly. For example, we can use similar triangles to measure the height of buildings, mountains or trees. We only need to set a similar triangles with a known height, and then calculate the height that cannot be measured directly by measuring the side length of similar triangles.

2. Determine the angle:

The angles similar to triangles are also proportional. This property can be used to determine the angle that we cannot measure directly. For example, we can use a similar triangle to determine the angle of a hole that cannot be directly entered.

3. Distance measurement:

In geography, similar triangles's attributes can be used to measure distance. For example, we can use a globe and a small light bulb to create a similar triangle, and then use the properties of the triangle to calculate the distance between any two points on the earth.

4. Engineering design:

In engineering, similar triangles can be used to design and measure structures. For example, architects can use similar triangles to design bridges, houses and other structures, and use the properties of triangles to ensure the stability of structures.

5. Photography:

In photography, similar triangles can be used to determine the real size of objects in photos. For example, we can use similar triangles to determine the size of buildings in photos.

6. sailing:

In navigation, similar triangles can be used to determine the position of ships. For example, we can use a similar triangle to determine the position of a ship relative to land.

7. Physical experiment:

In physics, similar triangles can be used to measure physical quantities that cannot be measured directly. For example, we can use a similar triangle to determine the weight of an object.

These are several types of triangles in practical application. In real life, the application of similar triangles is far more than that, and it is widely used in many fields.
