The Studymate Protractor can measure angles up to 180 degrees and also includes a 15 cm ruler for convenience in the classroom. It has a transparent design which makes it easy to see what you’re working on and a bevelled edge for easier marking and drawing. The protractor can measure degrees up to 180.
Why full circle is 360 degrees?

What is the measure of a full circle?
360 degrees
A full circle has 360 degrees, which means that 100% of the circle is 360 degrees. First convert into a decimal. If you multiply 360 by 0.20, you get the degree measure that corresponds to the percentage, which is 72.
How many 120 degrees does it take to make a full turn?
There are 120 degrees in a third of a full turn. To determine this, you need to start with a full turn which is 360 degrees.

Why are there 2pi radians in a circle?
One radian is equal to the angle formed when the arc opposite the angle is equal to the radius of the circle. Now, the circumference of the circle is 2 PI r, where r is the radius of the circle. So the circumference of a circle is 2 PI larger than its radius. This means that in any circle, there are 2 PI radians.
How do you use protractor?

What is the Universal bevel protractor?
A universal bevel protractor is a sophisticated protractor used by engineers, architects, and draftsmen to make accurate measurements of angles. There are 360 degrees in a circle and each degree is divided into 60 minutes, a universal bevel protractor allows for the measurements of minutes for a more accurate reading.
What is a protractor in math?
A protractor is a mathematical instrument used for measuring, drawing or plotting angles. Its scale, graduated in angular units or degrees, fringes the instrument’s upper-edge.
