What is right angle measurement
Cartesian measurement is a basic technique commonly used in geometry and engineering to determine whether two line segments or planes are perpendicular (i.e., the angle between them is 90 degrees). It is widely used in construction, mechanical processing, surveying and mapping and other fields. This article will combine recent hot topics and demonstrate the principles, tools and practical cases of rectangular measurement through structured data.
1. Principles and methods of right angle measurement
The core of right angle measurement is to verify the vertical relationship. Common methods include:
| method | Tools | error range |
|---|---|---|
| Pythagorean theorem method | Tape measure, laser range finder | ±0.5° |
| optical instrument method | Theodolite, total station | ±0.1° |
| Machine Tools Act | Right-angled ruler, square ruler | ±1° |
