A sextant is a traditional navigational instrument historically used, particularly at sea, to measure what specific angle?

Explanation

A sextant is a traditional navigational instrument historically used, particularly by sailors at sea, to measure the angle between the horizon and a celestial object, such as the sun, moon, or a specific star, using a system of mirrors to precisely align the two reference points. By carefully measuring this angle at a known time, navigators could calculate their approximate latitude, and with additional calculations, their overall position, well before the development of modern satellite-based navigation systems like GPS. Though largely superseded by modern electronic navigation technology today, sextants remain valued as reliable backup navigational tools, particularly in situations where electronic systems might fail.
