Because they have 9 sides
Only if you know what kind of polygon you have. If you know that you have a hexagon and one side is 1 cm, the perimeter is 6 cm. You only have to know the length of one side, since a regular polygon has equal sides. Perimeter or a regular polygon is the length of each side times the number of sides. You need to know both pieces to find the perimeter. ■
If every side of the polygon is the same length, then it is a regular polygon. If the measure of every internal angle of a polygon is the same as every other, then it is a regular polygon. The two always go together, so you need to check only one of the above criteria.
I can not tell you. It is because i do not know what shape the polygon is. You must tell me that first.
It is a regular polygon when its sides are of equal length and its interior angles are of equal sizes
Divide the polygon into triangles. Calculate the areas of the triangles and then sum these.
If it doesnt have 5 sides its not a polygon.
You know because the area is the distance inside a polygon and a perimeter is the distance outside a polygon.
its a 3-d trangle and i want to know if its a polygon or a polyhedron
A non polygon is a shape that doesn't meet the requierments to be a polygon. In order to be a polygon, a shape must have no curved lines and must be a closed shape.
pent, 5, polygon, 5 sided polygon,....... i dont know?!
are you asking for the angle measure of an angle inside a polygon? Not sure what you want to know.

I have know idea that is why i am asking it so answer it
A tetragon (a polygon with four sides) is more commonly known as a quadrilateral.
