A digon has two sides. It is a polygon in the mathematics of geometry. A digon also has two vertices.
a digon ']* * * * *There cannot be such a shape.
Two straight lines cannot enclose a space - therefore three lines is the minimum requirement for a polygon. I would like to note that a digon is a polygon and it has 2 sides. Therefore, the minimum is 2. However, some people call a digon an improper polygon since it contradicts the definition of polygon. A digon can only be made on a sphere, so the answer is never truly correct.
That one where it said dicot, i made a mistake. It is a digon
Yes. A digon can have 2 sides, but only in a spherical geometry. In normal Euclidean geometry both the monogon and the digon have just 1 side.
It is and it isn't. It is a degenerate polygon in Euclidean geometry but it can be a useful concept in some situations.
A 2 sided shape is called a digon
Although a polygon is usually thought of as a two-dimensional figure with at least three sides, there is nothing in the definition of a polygon that prohibits its use for the classification of a one-sided figure. A one-sided figure is known as a henagon or a monogon. A polygon, by definition, has as many vertices as it has sides, so a single-sided polygon would have to, in order to meet that criterion, curve in on itself so that the two ends of the side meet to form a vertex. In order for the polygon to not be curved, it would have to be made up of two straight lines (this figure is known as a digon). So no, a polygon cannot be a single straight line.

There are many shapes that have fewer than 3 vertices like the circle, hyperbola, semi circle, and many others. However if you are only talking about polygons then there is no actual shape with fewer than 3 vertices that you can find in a real life situation but they do have names for these shapes. A 2-sided polygon is known as a digon. A 1-sided polygon is known as a monogon. These shapes only exist in theory however and not in real life.
Ive been taught yes. Otherwise, you cant have a closed figure or straight lines. Both of which describes a polygon But when I looked it up on wikipedia for you (I left you a link, your welcome) I found the classifications saying that there are polygons with one (henagon/ monogon) and two (digon) sides. Why don't you take a look at the site? http://en.wikipedia.org/wiki/Polygon#Naming_polygons I also looked up their image on google. A henagon is a circle. They classified a point on it as a side, making it a polygon. Link: http://images.google.com/images?hl=en&q=henagon&gbv=2&aq=f&oq= A digon is more complicated, I can't even understand it. but here is a link to some images. There are 2 different digons I found: http://www.pballew.net/lune2.jpg http://images.google.com/imgres?imgurl=http://upload.wikimedia.org/wikipedia/commons/thumb/1/12/Regular_digon_in_spherical_geometry-2.svg/240px-Regular_digon_in_spherical_geometry-2.svg.png&imgrefurl=http://en.wikipedia.org/wiki/Digon&usg=__cvo67cucls1y356t_fenQcgE31E=&h=240&w=240&sz=25&hl=en&start=4&tbnid=UfE4uJUYp-NasM:&tbnh=110&tbnw=110&prev=/images%3Fq%3Ddigon%2Bpolygon%26gbv%3D2%26hl%3Den (Ull find 3 more on that link)
