"WebImagine a circle and a central angle in it. If the length of an arc that this angle cuts off the circle equals to its radius, then, by definition, this angle's measure is 1 radian.If an angle is twice as big, the arc it cuts off the circle will be twice as long and the measure of this angle will be 2 radians.So, the ratio between an arc and a radius is a measure of a central … " - Exact values and radians
