What is a 13-sided polygon?

No, a concave polygon cannot be a regular polygon.

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.

it will depend on the size of the polygon or, what polygon it is.

The definition of a irregular polygon is any polygon that is not a regular polygon.

Regular polygon Equilateral polygon Polygon with rotational symmetry

An equilateral polygon is a polygon where the length of all the sides of the polygon are the same length.

A convex polygon. I suspect that what you mean is a convex polygon.

Yes. A polygon is a closed figure.

A polygon is a Two dimensional figure that is closed.

Yes, a regular polygon is a type of polygon where all the sides and angles are equal.

Polygon B is an octagon.

Basically, a non-regular polygon is an irregular polygon. And if you don't know what that is, an irregular polygon is a polygon where all the sides aren't equal.

It is a convex polygon.

No it CANT be a polygon because its open a polygon has to be close

A polygon region is the area inside the boundaries of a polygon.

A circle with a polygon in it An inscribed polygon is any polygon that can fit within a specific curve or circle.

What polygon? Your asking "what are two names to describe a polygon" but haven't given a polygon...

A triangle in general is just a polygon. An equilateral triangle is a regular polygon.

It is a convex polygon.

A regular polygon is a polygon with congruent sides and interior angles.

an irregular polygon is a polygon that is the opposite of a regular polygon in a regular polygon the sides are the same and the angles are the same and irregular is the opposite.

Any angle can cut a polygon. Any angle can cut a polygon. Any angle can cut a polygon. Any angle can cut a polygon.

A polygon can be convex, which means Convex Polygon: A polygon that has all interior angles less than 180° Concave Polygon A polygon that has one or more interior angles greater than 180° A Complex polygon is neither convex or concave. A star polygon is an example of a complex polygon. If you look in google images, there are tons of pics of them.

Finding the perimeter of a polygon is finding how far it is in total along all the edges of the polygon; whereas finding the area of a polygon is finding how much space the polygon covers. The perimeter of a polygon forms the boundary around the area of the polygon.
