Given a circle find the measure of an arc

The video tutorial explains how to measure arcs in a circle, focusing on the concepts of central angles, minor arcs, and major arcs. It begins with an introduction to measuring the arc from point P to R to U. The tutorial then describes the central angle and how it defines the minor arc, which in this case is 40 degrees. Finally, it covers the calculation of the major arc by subtracting the central angle from 360 degrees, resulting in a major arc of 320 degrees.
