What is thetaStart and thetaLength?

In Three.js's CircleGeometry class there are the parametres thetaStart and thetaLength. As far as I can tell they make the circle crinkled. What are they for and how do they work?

These parameters can be used to describe a circle arc. The defaults are thetaStart=0 and thetaLength=2π, so they form a whole circle. A smaller value for thetaLength will describe only part of a circle, and you can use thetaStart to define the angle where that segment starts.
