In geometry, a full circle is properly an arc of 360°, but informally it may be used to refer to the angle measure subtending that arc.
(geometry) arc of 360 degrees

- Through a rotation or revolution that ends at the starting point.
1983, Dorothy Koster Washburn, Structure and Cognition in Art, page 138:
- Thus, patterns whose parts move about a point axis are called finite, because eventually the parts will move full circle to superimpose upon the original starting point […]
- (idiomatic) Through a cycle of transition, returning to where one started after gaining experience or exploring other things.
2001, Peter M. Coan, Taxi: The Harry Chapin Story, page 139:
- He'd begin with a premise and wrap it up at the end, full circle, the moral of the story hanging on the last word of the last line.
2012, John Schuster, Descartes-Agonistes: Physcio-mathematics, Method & Corpuscular Mechanism 1618-33, page 213:
- This therefore marks our return full circle to the optical proofs in the Diotprique with which our detective work began.
