no because the centre is the middle of it, whereas the origin is how it came to be named or where it came from
The centre of a coordinate plane is the point (0,0), also called the origin.
There is no special name for that. However, if the sides are also equal, it is called a regular polygon.
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.
A 17 sided polygon is called a heptadecagon. It is also sometimes referred to as a heptakaidecagon
No, a sphere is like a circle. A circle is a closed figure that is not a polygon. Also another definition it is a shape with all points the same distance from the origin (center). Remember if it had any edges you would have seen the they are sharp looking rectangles and other polygons have edges.
The centre of a coordinate plane is the point (0,0), also called the origin.
A 13 sided polygon is called a Tridecagon also a Triskaidecagon.
There is no special name for that. However, if the sides are also equal, it is called a regular polygon.
A 19-sided polygon is an enneadecagon (also enneakaidecagon or nonadecagon).
It is called a regular polygon. * * * * * Actually not. All its angles must also be congruent for it to be called regular.
A triacontakaipentagon is a thirty-five sided polygon. It may also be called a 35-gon.
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.
The 11 side polygon is called bysocleptron
A 17 sided polygon is called a heptadecagon. It is also sometimes referred to as a heptakaidecagon
A 16-sided figure is called a hexadecagon. Another name for this polygon is a hexakaidecagon.This polygon also has 16 vertices.
A tridecagon is a 13 sided polygon. Also called a triskaidecagon.
A polygon is any 2-dimensional shape with straight sides. Such a shape with sides of equal length would be called an equilateral polygon. If it is also convex (all the angles face the same way), then it would be called a regular polygon.
