Introduction to PolygonsPolygon Image Definition
Regular Polygon A regular polygon is a polygon which is equiangular (all angles are equal in measure) and equilateral (all sides have the same length).
Irregular polygon
An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure
Congruent Polygons
Two polygons that are equal in shape and size.
Introduction to PolygonsConcave Polygons can be cut by a straight lines in more than two points
Convex Polygons can be cut by any straight line in at most two points
