We measure angles using a tool called a protractor. A protractor is half of a circle. A protractor uses units called degrees to measure angles. A protractor can measure angles starting from the left or from the right. It measures from 0 to 180 degrees. 180 degrees is half of the measure of a circle.
Universal bevel protractors are also used by toolmakers, as they measure angles by mechanical contact they are classed as mechanical protractors. The bevel protractor is used to establish and test angles to very close tolerances. It reads to 5 minutes or 1/12Â° and can measure any angle from 0Â° to 360Â°. The bevel protractor consists of a beam, a graduated dial and a blade which is connected to a swivel plate (with Vernier scale) by thumb nut and clamp.
