What are the 4 types of polygon?

Excuse me, but I'm a bit curious about the Polygon concept you mentioned. Could you please elaborate on the four types of polygons you referred to? Are you referring to the classification based on the number of sides, such as triangles, quadrilaterals, pentagons, and hexagons? Or is there a different categorization you're referring to in the context of mathematics or geometry? It would be great if you could clarify and provide a brief description of each type, if possible.
