Radian - Wikipedia
The radian, denoted by the symbol rad, is the unit of angle in the International System of Units (SI) and is the standard unit of angular measure used in many areas of mathematics. It is defined such that one radian is the angle subtended at the centre of a circle by an arc that is equal in length to the radius. [ 2 ]
Radian - Formula, Definition | Radians and Degrees - Cuemath
Radian is the SI unit of measuring angles which is based on the arc length and the radius. 1 radian is equal to the angle subtended by an arc at the center of the circle whose length is equal to the radius of the circle.
