What is the condition of the angle in the European method of tachyometric distance measurement?

• A. It is fixed
• B. It is variable
• C. It is always obtuse
• D. It is irrelevant

Answer: (A)

In the European method of tachymetric distance measurement, the angle is fixed to a specific value. This fixed angle corresponds to the geometric principle that facilitates the calculation of distances using the tachymeter. By maintaining a constant angle, measurements can be taken in a way that simplifies the application of trigonometric formulas to derive distances. The fixed angle allows for standardized measurements, making the process more efficient and easier to replicate. This technique contrasts with other methods that may involve variable angles, which can complicate calculations and potentially lead to larger errors in distance estimation. Consequently, the fixed nature of the angle is integral to ensuring accuracy in the measurements taken using this method, highlighting its importance in surveying practices.
