Learning how to find the measure of a minor arc for a circle

The video tutorial explains how to measure arcs in a circle, focusing on minor arcs. It begins by defining different types of arcs and central angles. The instructor then guides students through solving a problem to find the measure of a specific minor arc, STP, using known angles and the properties of a circle. The solution involves calculating the unknown angle by subtracting known angles from 180 degrees, the measure of a straight line. The tutorial concludes with a recap of the solution and key concepts.
