- A circle contains 360 degrees.
Every circle contains 360 degrees. Each degree is of the total distance around the outside
of the circle. It doesn’t matter whether the circle is large or small; it still has exactly 360
degrees.
- When you think about angles, remember circles.
An angle is formed when two line segments extend from a common point. If you think of the
point as the center of a circle, the measure of the angle is the number of degrees enclosed by the
lines when they pass through the edge of the circle. Once again, the size of the circle doesn’t
matter; neither does the length of the lines.
Please refer to the figure below for clarification.
- A line is a 180-degree angle.
You probably don’t think of a line as an angle, but it is one. Think of it as a flat angle. The
