An astrolabe and a protractor are both instruments used for measuring angles. The astrolabe, an ancient tool, was primarily used in astronomy for determining the positions of stars and celestial bodies, while a protractor is a simpler, more modern device used mainly in geometry for measuring angles in two-dimensional shapes. Both tools share a circular design and allow users to read angles, but the astrolabe incorporates more complex features for astronomical calculations.
To read an astrolabe, level the plum bob, the degree scale, the altitude, and the protractor.
This is a protractor. It helps you measure angles.
