Sum of interior angles of polygon

Hello,

Thanks for uploading files of geometry.

In many of your files you said Sum of interior angles of any n-gon is (n-2)180. But that only works on simple polygons not on complex and star polygons. If a star polygon {p/q} is regular it's Sum of interior angles is (p-2q)180 for example for a pentagram {5/2} it is (5-2(2))180=(5-4)180=1*180=180 degrees.

I will be glad if you upload a file for all polygons.

Thanks, هيربد فودازى٢ (talk) 14:32, 17 July 2021 (UTC)
