In general, poly. Specifically, there are infinite prefixes. Examples include deca, octa, and penta.
octagon, hexagon
There is no official metric prefix for ten million, nor is there a Greek prefix that would work really well. In this case, you can go with the conventional n-gon format and call it a 10,000,000-gon ("ten million"=gon).
A shape with 25 sides is called a 25-gon. In geometry, the prefix “gon” denotes the number of sides a polygon has, so a polygon with 25 sides specifically is referred to as a 25-gon.
You call it a Chilligon. "Chilli" is Greek and means 100 and "gon" is the prefix.
An octagon is an eight-sided shape. The prefix is octa-, meaning eight. -Gon refers to the shape.
Five(5) Remember the names for the given number of sides of polygons. 3 ; Tri-gon (Triangle) 4 ; Tetra-gon (Quadrilateral ) 5 ; Penta-gon 6 ; Hexa-gon 7 ; Hepta-gon 8 ; Octa-gon 9 ; Nona-gon 10; Deca- gon. NB Notice all these 2-dimensional figures end in '---gon'. NNB The prefix names are from Latin, for the given number. NNNB ; Careful with 6 & 7 , 'Hexa' & Hepta' respectively. NNNNB Octa , for '8' as in Octopus, or October.
It gets its name from the Greek prefix icosa- meaning 20 and suffix -gon which means angle(s).
No - shapes ending with the prefix -gon are polygons, not prisms. A generic name for a six-faced polyhedron is a hexahedron.
In 2-dimensional geometry it is a 38-gon. You can look up its Greek-prefix name but most normal people would not bother.In 3-d geometry, there are very may possibilities: a pyramid with a 37-gon base, a bipyramid with a 36-gon base, a prism with 19-gon bases are three simple examples.
A polygon with 5000 sides is called a "pentacontapentagon." In general, the naming convention for polygons involves combining a prefix that denotes the number of sides with the suffix "-gon." For 5000 sides, the prefix "penta-" (meaning five) and "conta-" (meaning with 20) are used, along with "gon" to form the complete term.
This shape is called a triacontakaitrigon, where "triacontakaitri" is a Greek prefix and "-gon" identifies the figure as a polygon.
If you wish to communicate, then 135-gon. If you want to irritate, obfuscate or simply be pretentious that you might use the Greek prefix.
