Radian: a unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
Explanation: The radian is basically the angle measure, and the angle measurement in radians is equal to the arc length. Unit circle and radians both show the angle measures, in radian and degree terms. The equation for circumference is C= 2(3.14)r, the whole distance around a circle is 2(3.14) They are the same thing. Radians and Degrees are interchangeable, you can convert them into each other easily. I prefer degrees because by looking at the degree i can tell how much of the circle it will take up. When i look at Radians i have to use my unit circle, however i think Radians are much more pure because they are going to be a more precise number.
