What is the Meaning & Definition of polygon
 Means polygon that geometric shape that is made up of many sides, being the same willing either regular or irregular. The polygon word comes from the Greek and means "many angles". Polygons  are flat shapes that are also closed and that normally have from three  sides on (being square-different types of polygons or triangles). Polygons  are composed by several sides, which are those that give limit to the  figure and mark its surface, in addition to defining them in space. The sides of a polygon are always closed, so this type of geometric figures can be never unopened. When  two sides come together, or come together in a point forms an angle  that will be characteristic and distinctive of this type of  polygon-specific element, which may be larger or lower depending on type  of union of sides that is generated. This angle can never be 180 degree however because if so it would be a new segment or line. Other  elements that make up the polygon are diagonals, those straight lines  joining two or more non-adjacent vertices, the perimeter or sum of the  sides that make it up, the internal angles and the external. On  the other hand, regular polygons, which are composed of similar or  balanced sides together, have a clearly marked Center and an apothem or  the line that joins the Centre with one of its sides. Polygons according to the number of sides who have taken different names. Thus,  the most simple or basic are the triangles (polygons first which can  form since there are polygons of one or both sides), the Quad and the  Pentagon, respectively with three, four and five sides. Then they follow the hexagons, the heptagons, octagons, the eneagonos and the decanogos to then follow infinite way. A megagono is, for example, a figure that has a million sides.
