Explanation
Polygons have vertices where sides meet and angles at each vertex. Polygons are named by their number of sides: triangle (3), quadrilateral (4), pentagon (5), hexagon (6), etc. Regular polygons have all sides equal and all angles equal. The sum of interior angles depends on the number of sides. Polygons form the basis of geometry.
Example
A pentagon is a polygon with five sides and five angles.
