Author Name: Franklin Williams

When talking about measuring instruments, protractors usually come to mind. Traditionally, a protractor is made of a transparent plastic or glass that is used to in measuring the degree or radian of an angle.

The use of protractor can be traced back to as early as 1400 BC by an ancient Egyptian architect. Eight hundred years ago, European mathematicians are also noted to use protractors in preparing maps and navigational charts. It is also used by sailors in the eighteenth century to navigate ships and by the 20th century, it became the standard for mathematics|it is considered an instrument used for angle measurements.

Protractors are not only limited to the common semi circle shape but also comes in shapes such as a full circle, square, rectangle, sixth circle or quarter circles. Two sided and four sided folding protractors are also introduced. As innovations came with the advent of technology, protractors became more accurate, advanced, fast and easy to use. This is known as the digital or electronic protractor.

A digital protractor is a type of protractor that automatically measures the angle without the need of the user to read it manually from a scale. It is shown in digital display showing the angle measurement on the screen. Unlike the traditional protractor, digital protractors have many parts such as the on and off button, LCD, hold button used to stop the reading, and the zero button to reset or start again.

Types of protractor also includes semicircular protractor that contains two scales graduated up to 180 degrees in opposite directions. Next is the circular protractor that is graduated up to 360 degrees in clockwise direction. It is expansively used by engineering and architecture students. Military personnel use military protractors to help them determine the exact coordinates of their allies or enemies.

Lastly, the Universal Venier Bevel has a fixed dial or main scale with four sections from 0 degree to 90 degrees each.
