The star is a polygon, but not a simple one. It is not simple because parts of the lines forming its boundaries are inside the star. The outline of a star is a simple polygon.
polygons our stuff I do not know
it seems to me that the only polygon of your description is a square
A type of polygon is a rhombusial polygon, trysectalnict polygon, and a equilateral polygon.
A triangle (not traingle) is a polygon. It can be a regular polygon but need not be.
what are different parts of polygon

Well, for it to be a polygon it has to have: 1. Have straight sides ( circle is not a polYgon) 2. Have connect lines to form a figure 3. Must at least have 3 lines( triangles a polygon)
The regular polygon is congruent

Their angles will be the same sizes.
Polygon comes from two parts: Poly -> Many Gon -> angle So literally: poly-gon = many-angles. A polygon is a plane with more than two corners
A regular polygon has a center, much as a circle does. There are also the sides which are all the same lengths. Then there is the apothem which is any segment that goes from the center and is perpendicular to one of the polygon's side. Then angles are also parts and they are all the same. You might consider the perimeter a part and of course it is the sum of the sides.
Sure, you can divide a pentagon into 4 parts by drawing two diagonals from one vertex to the opposite vertex, creating four triangles inside the pentagon. So technically, yes, you can divide a pentagon into 4 parts. But good luck trying to fit them back together perfectly!
Irregular polygons have three or more straight sides forming the boundaries of the polygon. At least one of the sides or one of the angles is different from the others.
You use the same letter only once when naming a polygon (or parts of a polygon) to avoid ambiguity. If you have two line segments both labelled A, then you won't know which one you mean when you talk about segment A, right?
