How to create geometric shapes with a cavity inside in LibGDX?

Question

Java

I'm going to create a game using LibGDX in android studio. You need to make a hollow hexagon, inside which the character is located. But now I found a method for creating only rectangles and quadrangular objects. But even those without the possibility of creating a cavity inside.

To start, urgently run again to learn the school geometry course, then follow the basics of computer graphics, then run to the libgdx api. Now we turn on the thinker and understand how simple it is.
