Such a polygon is called a regular polygon.
If you mean a polygon, as opposed to a poygon, the answer is a hexagon.
No, they are not.
a rectangle
decagon
triangle
nothing....but then you cant evlove poygon-2 into poygon-z Well, nothing really... Unless you were intending to use it to evolve Porygon-2 to Porygon-Z.
If you mean a polygon then it can have 3 or more sides
pentagon look like
equiangular poygon
You evolve porygon by letting it hold the "up-grade" then you have to trade to evolve.
assuming you mean polygon. a polygon with 9 sides is a nonagon
No, a scalene triangle, for example, is a convex poygon but it is not regular.
