Working Principle of Vernier Protractor

Working Principle of Vernier Protractor Points : Working Principle of Vernier Protractor, Degree, Minutes, Seconds Many times while angles should be measured very precisely. The universal Vernier Bevel protractor can calculate angles accurately to 1/12 degree or 5 minutes. A fast review of the circle, angles and the units of extent associated with them will aid in considerate how to read this tool. Degree A circle, no material what size, contains 360 degrees. This normally written360° Angles are as well measured by degrees. Minutes But a degree were divided into 60 equal parts, each part would represent 1 minute. The minute is use to represent a fractional part of a degree. It is write 0° 0’. Seconds Very accurate work requires that the minute be sub-divided into smaller units known as seconds.
