Identifying Composite Figures and Circles

The video tutorial focuses on identifying and counting semicircles and quarter circles within complex composite figures. It begins with an introduction to composite figures, explaining that they are shapes made up of several smaller shapes. The tutorial then guides viewers through the process of counting semicircles, identifying two in the example figure. Following this, the video explains how to count quarter circles, finding a total of four in the figure. The tutorial concludes with a review of the final count: two semicircles and four quarter circles.
