How many degrees are in a circle?

Explanation:
A circle represents a full rotation about a point, and that full rotation is defined as 360 degrees. A degree is one part of dividing the circle into 360 equal parts, so completing the entire turn around returns you to the starting direction after passing through 360 degrees. This convention also aligns with radians, where a full circle equals 2π radians. So the measurement of a whole circle is 360 degrees. The other numbers correspond to partial turns: 180 is a straight line (half-turn), 90 is a right angle (quarter-turn), and 270 is three-quarters of a turn, not the full circle.
