180 degrees

270 degrees

360 degrees

A complete circle encompasses a total of 360 degrees. This concept can be understood by visualizing a circle and the way it is divided into equal parts. Each quarter of a circle represents 90 degrees, so when you consider all four quarters together, they total 360 degrees. This measurement is a fundamental aspect of geometry, as it helps in various calculations involving angles, arcs, and sectors of circles. It is commonly used in fields such as mathematics, physics, and engineering, making it an essential piece of information. Thus, the correct answer reflects the total number of degrees required to complete a full rotation around a point.
