TYPES:
Star polygons , regular polygons , irregular polygons , inscribed polygons , circumscribed polygons.


ELEMENTS:
Sides , diagonals , vertices , and angles.


Star polygon: is a particular polygon case with a star shape, created out of linking together non consecutive vertices of a regular polygons.

Inscribe polygon: they are polygons place inside circle so all the vertex of polygons.

Circumscribed polygons: they are polygons surrounding a circle ,being its sides tangent to the circle inside.


                                                                      POLYGONS PARTS

Sides: each of line segments that form a polygon.
Vertex: the point in which two sides meet.
Diagonal: segment line that connects non consecutive vertices.
Perimeter: the path around a polygon , the addition of all its sides.
Center:it is a point equidistant from all vertices.
Apothem: line segment from the center to the middle point


                                                              CLASIFICATION
Convex: when any line pass for 2 points.
Non-convex: when 1 line pass through the polygon it´s cut any parts.
Equiangular: all polygons that have angles, vertices and sides equal.
Equilateral: all sides are of the same length.
Regular: all vertices angles and sides are equals.
Irregular: show different angles and length for their sides.
