A sextant is a tool that measures angles. Navigators used sextants to measure the angle between a visible object, like the sun or a star, and the horizon. Using mirrors and a scale, the sextant provided navigators with precise measurements that allowed them to determine the distance between objects and calculate their latitude while at sea.Lexicon
