1. A radian is a unit of angle, that can be simply said as another way to express degrees. If I were to explain radians to somebody who didn't know what they were i would say, that they are simply another measurement you can use in place of degrees, and are often found on the unit circle. 2. Radians are found all around the unit circle and can be classified as angle measurements on the cirlce 3. The circumference of a cirlce is 2pi which alsocommonly appears when trying to find a radian measure either by multiplying or being equal to 360 degreees, which is also the size of a full circle. 4. Radians are another way to express degrees and are commonly transcribed between each other. I prefer degrees, because I then do not have to deal with pi as much. Degrees are more pure I would say because you will not finish with decimals and pi is a never ending number.
