Central Angles, Circle Arcs, Angle Measurement, Major Arcs vs Minor Arcs, Chords – Geometry

This geometry video tutorial provides a basic introduction into central angles, circle arcs, and angle measurement. It explains the difference between a major arc and a minor arc. A central angle always form a minor arc which is less than 180 degrees in angle measure. The major arc is greater than 180 degrees. A semicircle has an intercepted arc of exactly 180 degrees. This video contains plenty of examples and practice problems.
