There are an infinite number. A circle has no sides technically, a triangle has three, a rectangle has four, a pentagon has five, and so on like this.

6-hexagon

7-heptagon

8-octagon

9-nonagon

10-decagon

11-monodecagon-not sure on this one

12-dodecagon

13-tridecagon

14-not sure-maybe quartadecagon?

I'm not sure on the others, but they go on like this using Latin and Greek numerical word roots and the suffix -gon.

Answer From Hyusuf

henagon (or monogon) 1

digon 2

triangle (or trigon) 3

quadrilateral (or tetragon) 4

pentagon 5

hexagon 6

heptagon 7

octagon 8

enneagon (or nonagon) 9

decagon 10

hendecagon 11

dodecagon 12

tridecagon or triskaidecagon 13

tetradecagon or tetrakaidecagon 14

pentadecagon (or quindecagon) or pentakaidecagon 15

hexadecagon or hexakaidecagon 16

heptadecagon or heptakaidecagon 17

octadecagon or octakaidecagon 18

enneadecagon or enneakaidecagon or nonadecagon 19

icosagon 20

icosihenagon 21

triacontagon 30

tetracontagon 40

tetracontaheptagon 47

pentacontagon 50

hexacontagon 60

heptacontagon 70

octacontagon 80

enneacontagon 90

hectagon (also hectogon) 100

chiliagon 1000

myriagon 10,000

decemyriagon 100,000

megagon 1,000,000

apeirogon (infinite)

The more sides a shape has, the more it looks like a circle.

a decemyriagon may look like a circle at first, but it's just a shape with 100,000 sides.

I hope this helped!
