SL 3.4
An arc is part of the circumference of a circle. It is defined by the radius r of the circle and the angle θ that the arc "sweeps out" over the circle's perimeter.

More than just introducing a new kind of shape, this gives a new way to measure angles called radians. The angle θ, in radians, is the length of the arc divided by the radius r.
