Polygon Properties and Diagonals

The video tutorial explains how to name polygons based on the number of sides they have, covering polygons from three to twelve sides, and introduces the concept of naming polygons with more than twelve sides using the 'endon' method. It also defines diagonals in polygons and provides a formula to calculate the number of diagonals, using examples from triangles to hexagons and extending to a 32-sided polygon.
