It is read off the azimuth scale, possibly magnified with a so-called microscope. say, 32 degrees, ll minutes. finer degrees of reading-out are possible with some types. This type of theodolite operation is not too different in principle than taking bearings on objects with a magnetic compass, and reading off the direction in degrees.
The angle of inclination.
the measure of an angle is the degrees of an angle.
The measure of the exterior angle.
No cheating!

Transit theodolites (or just 'Transits') are those in which the telescope can rotate in a complete circle in the vertical plane, whereas the rotation in the same plane is restricted to a semi-circle for non-transit theodolites
Theodolites were used in old times for surveying, mapping, and construction projects. They helped measure horizontal and vertical angles accurately, allowing for precise calculations of distances and elevations. Theodolites were essential tools for creating detailed maps, designing infrastructure, and aligning structures with precision.
Most theodolites have no "permanent" adjustments, since they are used to measure angles, both horizontal and vertical.
Surveyors use theodolites to measure angles in the horizontal and vertical planes with high accuracy. This allows them to determine directions and elevations of various points on the land they are surveying. The data collected from theodolites is essential for creating maps, construction projects, boundary delineation, and other surveying applications.
They are surveying instruments used to measure angles.
Disc angle has main two angle : 1. Vertical angle 2. Horizontal angle
the special type of theodolite used to measure horizontal and vertical distance and horizontal angle.
The angle of inclination of the Leaning Tower of Pisa was calculated using trigonometric methods and measurements of the tower's height and the horizontal distance from its base to the vertical line directly above its foundation. Surveyors and engineers have historically used tools like theodolites and clinometers to measure the angle of tilt. By comparing the height of the tower to the horizontal displacement, they could determine the angle of inclination, which has been observed to be approximately 3.97 degrees as of recent measurements. This angle has changed over time due to stabilization efforts and geological factors.
A horizontal angle is an angle between lines on a horizontal plane.
this is horizontal: ---------------------------- / / this is at an angle: / / /
Slope is the angle compared with the horizontal, where the horizontal is 90° to the vertical, which can be measured with a plumb line. So, put a weight on a string, measure the angle of the string to the angle you are measuring, subtract 90° and that will give you the slope.
20 degrees is a measure of angular displacement. This cannot be converted to lateral (horizontal) displacement.
