Minor arc
minor arc
The relation between the arc of length and the central angle is that the arc of length divided by one of the sides is the central angle in radians. If the arc is a full circle, then the central angle is 2pi radians or 360 degrees.
With a central angle of 180° it is a straight line and so the arc is a semi-circle
