Radians - determine angle from arc length and radius - Question As well as using degrees, angles can also be measured using what are known as **radians** (rad). Radians are defined with relation to a circle, with there being exactly 2\\(\pi\\) rad in one full circle. The below diagram shows a circle with a radius of 5 m. There is an angle \\(\theta\\) which corresponds to an arc length of 10 m on this circle.
