It is a quality of some shapes which some of their parts are reflections of these.
- REFLECTION SYMETRY: it 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.
- SIMETRY AXIS: it 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.Syimetric points are on a perpendicular line to it.
- CENTRAL SYMETRY: it 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.Symetric of points are collinier with the center.
- GEOMETRIC SYMETRY: it is a kind of symetry which follows accurarely the geometric symetry rules.
- APPERENT SYMETRY: it is the quallity of shapes or objects which show an obvius symetry but not every point or element follows accurarely the geometric symetry rules. It happens very frecuently in nature.
- SYMETRICAL BALANCE: It´s a way to organice parts of an image´picture or drawing so one side duplicates or mirrors the other. The opposite way is called Asymetrical Balance.
