Angles can be named in three ways: By three capital letters, with the vertex letter in the middle. For the circle with center O above, AOB is a central angle since its vertex, O, is also the center of the circle. The point where {eq}EG {/eq} and {eq}EF {/eq} meet is {eq}E {/eq}. An angle can be defined as a space between two intersecting lines meeting at a common point. Angles can occur in any position on the coordinate plane, but for the purpose of comparison, the convention is to illustrate them in the same position whenever possible.
