6-1 Properties and Attributes of Polygons - Geometry Help

The video tutorial covers the properties and attributes of polygons, including key terminology such as vertex, sides, and diagonals. It explains different types of polygons, including triangles, quadrilaterals, and more, up to a 13-sided figure called a tarvagon. The tutorial also distinguishes between regular and irregular polygons, as well as concave and convex polygons. It provides formulas for calculating the sum of interior angles and explains that the sum of exterior angles of any polygon is always 360 degrees.
