Poly is the word for many, probably Greek.
What is the name of 30 side polygon?
A 30-sided polygon is called a triacontagon. The prefix "tria-" is derived from the Greek word for three, and "contagon" is derived from the Greek word for angle. Therefore, a triacontagon has 30 sides and 30 angles.
What is a 7-sided polygon called a heptagon and a septagon?
A 7-sided polygon is called a heptagon. The word derived from Greek. If it derived from Latin it might be called a septagon, but that is not the case.
What do you call a 9-sided polygon?
A nine-sided regular polygon is called a nonagon or an enneagon. The word nonagon is a hybrid-word where the prefix non- derives from Latin while the suffix -gon derives from Greek.
Is a heptagon the same as a septagon?
The correct name in English for a 7-sided polygon is "heptagon." The word "septagon" is used incorrectly by some who do not understand that the names of polygons are derived from Greek, not from Latin. The Latin word for "seven is "septem" but the Greek word is "hexa."
