As the picture below shows, an arc is a part or a portion of a circle.
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'. Identify arcs
Identify the major and minor arcs in the circle below.
Answer The measure of an arc = the measure of its central angle. Therefore the measure of =85 The measure of =360° −85°=275°
