A theodolite is an optical instrument used primarily for measuring horizontal and vertical angles in surveying and construction. Its main functions include establishing precise angles for mapping terrain, aligning structures, and setting out points in construction projects. Theodolites can also be used for triangulation, leveling, and determining elevations, making them essential tools in civil engineering and geodesy. Modern theodolites may include electronic features for enhanced precision and data collection.

A theodolite is used to measure angles of a plane. This can be both vertical or horizontal, and it is used with high precision.

Dumpty level can be used only for vertical measurements while a theodolite functions in both horizontal and vertical measurements.

A theodolite is a surveying instrument used to measure horizontal and vertical angles. It requires a separate instrument to measure distances. A total station is a surveying instrument that combines the functions of a theodolite and distance measuring device, allowing for simultaneous measurement of angles and distances.
principle of theodolite is based on the principle of trigonometry.
Theodolite light is the correct spelling
least count of theodolite is 1 second
5 mm is the least count of theodolite.
A theodolite measures angles and axis needed for site surveying. The horizontal and vertical angles are measured using a theodolite. A theodolite is actually a mounted telescope used in building.
A theodolite that shows a digital rather than analogue display.
