What is the name of a 45 sided polygon?

Answer 1

45-gon. really, its easy. there are only a few exceptions to the way that works:

3- Triangle (scalene, isosceles, equilateral; equiangular, obtuse, acute)

4- Quadrilateral (square, parallelogram, trapezoid, rectangle, rhombus)

5- Pentagon

6- Hexagon

7- Heptagon

8- Octagon

9- Nonagon

10- Decagon (Decade)

11- hendegon or endegon

12- Dodecagon

After that, they get lazy, naming them the number of sides + "gon" ex.

13- 13-gon

14- 14-gon

etc.

It goes on until 100

100- Centagon (Century)

Then its back to 101-gon

It goes the lazy way until 1,000,000. This one I just heard about, but I don't know if it's true or not.

1,000,000- Milinagon (Millennium)

(The one million sided polygon is actually called a hecatommyriagon)
