High Quality 0~360 Degree Universal Digital Bevel Angle Protractor

A protractor is an instrument used to measure the degree of an angle, which is generally semi-circular. The diameter of the semicircle is the zero scale line of the protractor, and the center of the diameter is the center of the protractor. The scale on the semicircle is the degree used to measure the angle, ranging from 0 to 180 degrees.

As the name implies, it is an instrument used to measure the degree of angle, which can measure angle, inclination, verticality and levelness. In addition, the protractor is also a drawing tool, which can draw angles, vertical lines and parallel lines. It can be used as an internal and external right-angle ruler to open and close. It can also be used as a long and short ruler to read accurately and intuitively, and draw a circular dimension of the specified size. The protractor is usually made of plastic or iron and is often used with a compass.
