Mathematics tends to use Greek words, or a combination of words, to describe geometric shapes. Decagon is composed of two parts, based on the Greek words: . deca- (a transliteration of ÎÎκα), which means "ten" . -gon (from the Î3ωνÎα, transliterated as "gonia") which refers to the corner or "angle". So a "decagon" is literally a "ten cornered" or "ten angled" shape. A "polygon" is also made up of two parts, based on the Greek words: . poly- (from ποÎ"Î"οÎ, transliterated as "populace"), which means "many" . -gon as about the meaning of the corner or "angle". Thus, a "polygon" is, literally, a "many cornered" or "many-angle" shape. [Transliteration is the re-writing of the letter of the original language in the letter of our language with a similar sound.] . As an aside, the three-sided and four-sided shapes do not follow this trend, for the case that I made: . a triangle without a doubt, it would be called a triagon (even though "triangle" is a translation of the Greek); . a ring, certainly, it would be called a tesseragon. since tria is the Greek word for 3 and tessera the Greek word for 4.
