What is the measure of one radian

The video tutorial explains the concept of radians, starting with the definition of a circle and its radius. It describes how a radian is the arc length equivalent to the radius of a circle. The tutorial then introduces central angles, explaining how they are formed by rotating rays about a circle's center. It further elaborates on measuring angles in radians, illustrating how multiple radians fit around a circle and introducing the mathematical constant π as the measure of half a circle in radians.
