Understanding Central Angles in Polygons

The video tutorial explains how to find the central angle of a polygon by dividing the circle's 360 degrees by the number of sides. It uses examples of a triangle and a square to illustrate the concept. The formula for calculating the central angle is given as 360/n, where n is the number of sides. Additional resources are available on the website.
