Oh, dude, you're really making me work here! Okay, let's see... so, a polygon with 11 sides is called a hendecagon, then you've got a dodecagon with 12 sides, a tridecagon with 13 sides, a tetradecagon with 14 sides, a pentadecagon with 15 sides, a hexadecagon with 16 sides, a heptadecagon with 17 sides, an octadecagon with 18 sides, an enneadecagon with 19 sides, and finally, a 20-sided polygon is called an icosagon. Like, who even uses these names in real life, right?
Sure, polygons with 11 sides to 20 sides are as follows: 11 sides - undecagon, 12 sides - dodecagon, 13 sides - tridecagon or triskaidecagon, 14 sides - tetradecagon, 15 sides - pentadecagon, 16 sides - hexadecagon, 17 sides - heptadecagon, 18 sides - octadecagon, 19 sides - enneadecagon or nonadecagon, and 20 sides - icosagon.
Oh, how wonderful! Let's paint a happy little picture with our shapes. A polygon with 11 sides is called a hendecagon, while a polygon with 12 sides is called a dodecagon. Moving along, a polygon with 13 sides is called a tridecagon, and so on up to a 20-sided polygon, which is called an icosagon. Just remember, each shape is unique and special in its own way.
