What is the degree measure of a full circle?

A full circle measures 360 degrees. This is a foundational concept in geometry that defines the total angle formed when one completes a circular path. The circle, as a two-dimensional shape, is divided into parts where each degree represents a unit of angle measurement.

In practical applications, understanding that a full rotation around a point equals 360 degrees is crucial for various fields, including mathematics, physics, and engineering. For instance, when measuring angles for rotations or in scenarios involving circular motion, this 360-degree measure is consistently employed.

The other options present degrees that do not correspond to a full circle: 180 degrees represents a half-circle, 540 degrees indicates one and a half circles (one complete rotation plus another half), and 720 degrees accounts for two full rotations around a point. Recognizing the unique measurement of 360 degrees as the standard for a complete rotation is essential to mastering topics related to angles and circles in geometry.
