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
n-gon
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.
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.
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
