Draw polygon

Hello,

so i would like to draw some polygons but i don't know how.

In theory what i would like to do is to make an array of vertecies (x,y,z) ordered clockwise and then put them through some function which would draw my polygon. Does a function like that exist in unity?

I would like it to be like a quad (rendered only from one side).

Could you give me some simple C# code ... for some simple polygon? Like a square or a triangle.

Thank you!
