Q. An instrument called “Theodolite” is used in which among the following ?
Answer: Measuring horizontal and vertical angles in triangular networks
Notes: A theodolite is a precision instrument that is used to measure the angle of inclination, or slope, of an object in relation to a horizontal plane. It is commonly used in surveying and construction work to measure and determine the elevation, slope, and horizontal and vertical angles of a specific object or area. Theodolites typically consist of a rotating telescope mounted on a tripod, with graduated circles that allow for the precise measurement of angles. They are commonly used in conjunction with other surveying instruments, such as levels and total stations, to create detailed maps and plans of an area.
