Vocabulary of Art

Polygons:
We learn learned how to do :
-Triangle , square , hexagon, pentagon ,hepatgon ,octogon and dodecagon.
Stars Polygons:
The polygons crashed can not get in the way you told abd not.
According to the number of vertices that a non-crashed polygon has, we can obtain none, one or several stars.

There are starry polygons that are called false stars because they are formed by two polygons.
I  learn to do this stars : pentagon star , heptagon star , octogon star , dodecagon star.
Symmetric:
Symetrical balance:it is a way to organize parts of a image , picture or drawing so one side uplicates or mirrors the others . The opposite way is called asymmetrical balance .
Symetry:It is a quality os somme shapes which some of their parts are reflection of others
Reflection symmetric: it is a shapes  quality which is formed by 2 halves facing each other whith an axis or fold line between as if both sides were mirror images of each other.
Symetri axis: It is a line which divides a sahpe into 2 parts symmetric halves. Every element of the shape is reflected on the other side and at same distance from the axis .Symmetric points are an perpendicular line ot it .
Central symetry: Its is a reflection of an object through a point called the symmeric center .Every symmetric point is on other side and at the same distace from the center symmetric . Symmetric pair of point are collinear whith the center.
Geometric symmetric : It is a kind symmetric followa accurately the geometric symmetric rules.
Apparent symmetric: It is a quality of shapes or objects which show anobvius symmetric , but not every points or elements followa accuarately the geometric symmetry rules .It happens ery frequently in nature.
