Intercepted Arc

An intercepted arc is the arc that is formed when segments intersect portions of a circle and create arcs.These segments in effect 'intercept' parts of the circle. The picture below shows examples of intercepted arcs.
Note: The examples below use chords to create the intercepted arc. However, tangents, secants can also create intercepted arcs.

Arcs are grouped into two descriptive categories:
1) minor arc
2) major arc
In the circle on the left, there is both a major arc and a minor arc. Look at the circle and try to figure out how you would divide it into a portion that is 'major' and a portion that is 'minor'.
