What is the height angle?

The height angle is the angle of the angle created by the horizontal plane in which the observer is located, and the object above the horizontal plane. The observer stands at the top of the angle. The intersection of the angle rays with a vertical line from the building to the horizontal plane forms a true triangle. There are a number of ways to determine this angle, given the known height and distance, and devices such as sextants can be used to measure angle. Due to the known height angle, it is possible to determine the height and distance of the observed object.

If the observer is directly below the object whose height angle is measured, the angle is 90 degrees. The object on the same horizontal plane as the observer has an altitude of zero stages. The level of an angle of altitude may drop between the two values.

Although sextant is a tool traditionally used to measure the angle of increasing the heavenly object navigation purposes can be used to determine the angle of increasing any object. For the use of the sextant, the observer holds the instrument of up to one eye and points to the raised object. MarkedThe degrees on the sextant indicate an angle created by the horizontal plane of the observer and the intersecting beam that points to an elevated object.

geometric and mathematical concepts associated with the right triangles can be used to determine unknown distance and angle values ​​and simple trigonometry can be used to solve unknown values ​​if at least two are known. If the height of the object and the distance between the observer is known, the height angle may be determined by finding the angle thong - the height to the distance. If the angle and the height or distance are known, the same way may be unknown. It is also possible to determine the angle of height if only one known value is given, although it requires the use of more advanced trigonometric concepts.
