A dodecagon
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.
an arrow is or isn't a polygon?
There is no such thing as a largest polygon, just as there is no largest number. You can always add one more to a number - or add one more side to get a bigger polygon.
A dodecagon
The largest exterior angle measure is 120o. It is the exterior measure of an equilateral triangle (which is a regular polygon).
I stand corrected the largest sided polygon is a myriagon. Source the MIT. 1000 sided
There is no mathematical limit to the number of sides that a polygon can have. As the number of sides increases the polygon will become more and more like a closed curve - a regular polygon will become like a circle. The size of the polygon and accuracy of measurement will determine when it is no longer possible to distinguish between the polygon and the curve. Nevertheless, the two shapes will be mathematically different objects.
The width of a polygon will depend on its shape. For a polygon, in general, it is the length of the largest diagonal. However, for rectangles of squares it often refers to its smaller sides.
infinite
It is: (n-2)*180 = interior angles whereas 'n' is the number of sides of the polygon
At most two sides of a polygon go through any point of intersection.
you can have just about as many as you pleas, just dont try to draw a polygon with 1 million sides
There is no limit to the number of sides that a polygon can have. Mathematically, a circle is equivalent to a polygon with an infinite number of sides.
The polygon may have 2n sides, where n is any whole number greater than 1
