In geometry, a decagon is a ten-sided polygon or 10-gon.

Also, what is a 7 sided shape called? In geometry, a heptagon is a seven-sided polygon or 7-gon. The heptagon is sometimes referred to as the septagon, using "sept-" (an elision of septua-, a Latin-derived numerical prefix, rather than hepta-, a Greek-derived numerical prefix; both are cognate) together with the Greek suffix "-agon" meaning angle.

Also to know is, what is an 11 sided shape called?

In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon. (The name hendecagon, from Greek hendeka "eleven" and –gon "corner", is often preferred to the hybrid undecagon, whose first part is formed from Latin undecim "eleven".)

What is a 21 sided shape called?

Greek for 21: Είκοσι καί ένα (Icosi kai hena = Twenty and one), but also just: Είκοσι ένα (Icosi hena = Twenty one). A polygon with 21 sides is therefore called a: Icosikaihenagon, but also a Icosihenagon.

Can a polygon have curved sides?

No. A polygon by definition has straight line segments as its sides. If a geometrical figure has curved sides, it is not considered a polygon. A regular polygon has an interior angle that is twice the exterior angle.

Is there a shape with 2 sides?

In geometry, a digon is a polygon with two sides (edges) and two vertices. Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be easily visualised in elliptic space.
