SYMETRY

REFLECTION SYMETRY:  Is a shape quality which is form by two halves facing each other with an axis or fold line in between as if both sides were mirrow images of each other.
SYMETRY AXIS: Is a line which divide a shape into two simesetic halves.Every element of the shape is reflected on the other side and at the same distance from the axis.
CENTRAL SYMETRY:  Is the reflectan of an object through a paint called the symetry center. Every symetric points is an the other side and at the same distances from the center of symetry.
GEOMETRY SYMETRY:  Is a kind of symetry which follows accurarely the geometric symetry rules.
APPARENTS SYMETRY: Is the quallity of shapes or objects which show an obvius symetry but not every point or element follows accurarely the geometric symetry rules.
SYMMETRICAL BALANCE: It is a way to organize parts of an image, picture or drawing so one side duplicates or mirrors the other.

POLYGONS

STAR POLYGONS: It is a particular polygon case with a star shape, created out of linkong together non consecutive vertice of a regular polygon.
INSCRIVED POLYGONS: They are a polygons placed inside circles so all the vertices of the polygons are placed on the circle.
CIRCUNSCRIBED POLYGONS: They are polygons surrounding a circle, being its sides tangent to the circle inside.


POLYGONS PARTS

SIDE: Each of the line segments that form a polygon.
VERTEX: The point in whith two sides or edges meet.
DIAGONAL: Segment line that connects non consecutive vertices.
PERIMETER: The path around a polygon, the addition of all its sides.
APHOTEM: Line segment from the center to yhe mindpoint of one of its sides.
