Area of Segments and Sectors

The video tutorial explains how to calculate the area of a segment in a circle. It begins by defining segments and sectors, then demonstrates how to find the area of a segment by subtracting the area of a triangle from the area of a sector. The tutorial covers using formulas and alternative methods, such as subdividing triangles, to achieve the same result. The video concludes with a summary of the methods discussed.
