Introduction to Polygons

The video tutorial introduces polygons as many-sided shapes and explains the differences between regular and irregular polygons, highlighting that regular polygons have equal side lengths and angles, while irregular ones do not. It further distinguishes between convex and concave polygons, noting that convex polygons have all interior angles less than 180 degrees, whereas concave polygons have at least one reflex angle. The tutorial also covers the classification of polygons based on the number of sides, providing names for polygons with three to ten sides, such as triangle, quadrilateral, pentagon, and so on. The video concludes with a brief summary of these concepts.
