When surveying land, what unit is used for measuring small angles?

When surveying land and dealing with small angles, the use of minutes is important due to its precision in measurements. One degree is subdivided into 60 minutes, allowing for a more detailed angle calculation when surveying, which often requires increased accuracy for small angles. This is especially useful in fields like land surveying where small variations in angles can significantly impact the overall measurements and layout of a property.

While other options like degrees, gradians, and seconds are also units of angular measurement, minutes comes into play specifically for calculating and expressing smaller angles within the broader context of degrees. In practice, measuring smaller angles in minutes ensures that surveyors can achieve the level of accuracy necessary for effective land assessment and construction planning.
