Angle-measuring devices are available in several types. The most popular and widely known is a disk protractor - a half-disk made of glass or plastic. The material is see-through, which makes it easier to see and measure angles in small geometric objects and drawings. The instrument has a special scale with degrees from 0 to 180. A bevel protractor is a more complicated variation of this device, it has a moving arm connected to a fixed arm with a dial, and can be applied to mark or estimate angles in construction, design, technical drawing, and similar applications.
