Emilia Chan · Answer 2

The radian is a unit of measure for angles used mainly in trigonometry. It is used instead of degrees ... As seen in the figure above, a radian is defined by an arc of a circle. The length of the arc is equal to the radius of the circle. Because of this the radian is a fixed size no matter what the size of the circle is.
