How Many Degrees Are in a Circle?

There are exactly 360 degrees in any circle. A circle is a two dimensional shape that consists of a consistently curved line that continues until it meets itself.

Angle measurements are used to measure the amount of rotation between two lines. To determine the amount of degrees in a circle, draw an imaginary line along the radius at any point from the center to the edge. From this line, measure the angle using a protractor that is centered at the inside point. Starting from a horizontal line, a vertical perpendicular line is 90 degrees, and a second horizontal line is 180 degrees. A second vertical line is at 270 degrees, before reaching 360 degrees at the starting point.
