Answer Details
The survey instrument used for measuring horizontal and vertical angles on the field is the theodolite. It is an optical instrument that has a rotating base and a telescope mounted on it. The theodolite is used to measure angles between two points on the ground, which is important in surveying and construction work. The horizontal angle is measured by rotating the theodolite on its base, while the vertical angle is measured by tilting the telescope up or down. The theodolite is a precise instrument that is commonly used by surveyors and engineers to measure angles and distances accurately.
