What is polygon with more than 4 sides?

Polygons with More than Four Sides. Although triangles and quadrilaterals are the polygons you meet most often and the ones about which you have the most information, there are others. The other polygons have more sides, more vertices, more angles, and more diagonals, and there are a few rules they all follow.
