Full Rotation

This is a "full rotation" or "revolution" or "complete turn" or "full circle"

Other ways of saying it:

"I gave the wheel one complete turn looking for holes"
"It was spinning at 200 revolutions per minute" (but people usually say "RPM" instead of "revolutions per minute").
"Doing a 360" means you spin around completely once (spinning around twice is a "720").
"It completed one cycle", meaning it went around exactly once.
"She went full circle on liking carrots". So maybe she originally liked carrots, then hated them, now she likes them again.

This image of a protractor shows
that a full rotation is 360°

Also:

Half a rotation is 180°
(called a Straight Angle)

Quarter of a rotation is 90°
(called a Right Angle)

And a full rotation is also equal to 2π Radians, so here are some equivalent values:
