And this is true of any polygon.

It's a regular polygon, all the sides are the same.

You are graphing polygon ABCD in the coordinate plane.

Actually, there's a polygon tool here.

Regular polygon, all the angles and all the sides are congruent.

And you can do that with an arbitrarily shaped polygon.

Regular polygon, so that means that all of the angles are congruent.

And it's a regular hexagon, so all the interior angles are going to be the same.

So someone told you that they had a 102 sided polygon

But I'll show you how to always prove it for any polygon.

So if I draw any polygon, and I'll draw a triangle since that's what this question is about.

So the best thing to do, if you have a polygon, is to count the triangles in it.

And I didn't draw it that regular, but we can assume that all of these are each 120 degrees.

So it's a good thing to know that the sum of the exterior angles of any polygon is actually 360 degrees.

So, if I have an S sided polygon, I can get S minus two triangles that perfectly cover that polygon

And I think you'll find, that no matter what polygon you draw, all of the exterior angles are going to add up to 360 degrees.

So now hopefully, if I gave you a 20 sided polygon, you can figure out how many times can I fit triangles into it.

But I want you to draw random polygons with angle measures, because you know what the angles all have to add up to in a polyogon.

What is that thing reduced to lowest terms?

No star polygons with fewer than 5 points exist, and the construction of a normal 5 pointed magic star turns out to be impossible.
