The video tutorial explains polygons as simple closed shapes formed by straight line segments. It covers how polygons are named based on the number of sides, such as triangles, quadrilaterals, pentagons, and hexagons. The tutorial also discusses how to calculate the perimeter of a polygon by summing the lengths of its sides, regardless of the number of sides.
