A theodolite is a precision instrument used to measure angles in both horizontal and vertical planes. It consists of a rotating telescope mounted on a base, allowing it to be adjusted to measure angles accurately. Theodolites are commonly used in surveying and construction to determine angles between points, helping create precise maps and layouts. The instrument is essential for tasks like land surveying, building foundations, and setting boundaries. Modern theodolites may also include digital features to measure angles more easily and record data for further analysis.
