In any and all circles, the ratio of the circumference to the diameter is a constant called 'pi' ~ 3.14159 and since a full circle contains 2 pi radians = a constant 360 degrees, then the radian itself is a constant angle ~ 180/3.14159 = 57.3'.

raidans is just another way of expressing the size of an angle. pi radians = 180 degrees.

An informal definition: If you take a radius of a circle and wrap it around its circumference then the angle which that arc will make at the centre of the circle is 1 radian.More formally, a radian is 1/(2*pi) of a whole angle.

degree and radian are juest unit measurment of angle

The radian measure IS the arc length of the unit circle, by definition - that is how the radian is defined in the first place.
