Use the definition of a radian and you see that there are 2 pi radians in a circle (circumference). Therefore, 2 pi radians are equal to 360 degrees. > > Let me know if you think this is a good enough proof for what you asked. > > Good question.
that's very clear.
but mine question is..,
Is the concept of angle in a Circle(i.e.360degrees)is an *Axiom*?
