Introduction- how to use a protractor to measure angles:
In this lesson let me help you on how to use a protractor?In geometry, a protractor is a circular or semicircular tool for measuring an angle or a circle. The units of measurement utilized are usually degrees.
Some protractors are simple half-discs; these have existed since ancient times. More advanced protractors, such as the Bevel Protractor have one or two swinging arms, which can be used to help measure the angle.
Concept- How to Use a Protractor to Measure Angles:
The two most common units of angular measurement are the angle and the radian. This could also help us on radius of curvature
The angle (°) is the unit familiar to lay people. One angle (1°) is [1 / 360] of a full circle. This means that 90o represents a quarter circle,180° represents a half circle,270° represents three-quarters of a circle, and 360° represents a full circle.
