How many sides does a 12- gon have?
12. Whatever number you say before '-gon' is referring to the number of sides in the shape. However, 12-gon (or 20-gon, or whatever) is not the official name of any polygon but is commonly used. the commonly used name is a do-decagon
How do you name a polygon with more than 12 sides?
n-gon
What is a 15-sided shape called?
Pentadecagon actually, no, it is called a fifteen-gon, or fifteen-a-gon. anything more than 12(dodecagon) the name of the polygon is just the number of sides, and "gon" at the end.
What is a 97 sided shaped called?
any shape after 12 sides is just called the number sides - gon. for example: 97 is a 97-gon (pronounced: ninety seven gon). this works for any other number sides except 3,4,5,6,7,8,9,10,12. further examples are 11-gon, 15-gon, 47-gon, 101, gon... these go up until the angle measure of any regular polygon is exactly 180 degrees or as close as possible (179.99999...) making it a circle.
What are all the names of regular polygons?
3 sides = Triangle 4 sides = Quadrilateral 5 sides = Pentagon 6 sides = Hexagon 7 sides = Heptagon 8 sides = Octagon 9 sides = Nonagon 10 sides = Decagon. 12 sides = Dodecagon any other number after these or a shape with 11 sides .. you use the number of sides and put "gon" after.. for example if you have 13 sides. you would put 13-gon
