Polygon – a closed figure with segments as sides.

Polygon – a closed figure with segments as sides.

Definitions Convex – All the vertices of the polygon point “out”. Concave – A

Definitions Convex – All the vertices of the polygon point “out”. Concave – A polygon with at least one of the vertices pointing “in”.

Definitions Equilateral – all sides of a polygon are congruent Equiangular – all angles

Definitions Equilateral – all sides of a polygon are congruent Equiangular – all angles of a polygon are congruent Regular – a polygon is both equilateral and equiangular
