Answer:
Step-by-step explanation:
1. Timekeeping: The astrolabe can be used to measure the time of day or night by aligning the position of the Sun, stars, or other celestial bodies with the appropriate markings on the instrument.
2. Astronomy: The astrolabe can be used to study the movement of celestial bodies and to make observations of the stars and planets. It can also be used to measure the distance between stars and to determine the positions of the stars relative to each other.
3. Surveying: The astrolabe can be used for surveying by measuring the angles between objects and determining distances based on those angles. This technique is known as triangulation.
