I'm working on ArcMap 10.3.1. I'd like to retrieve the values of all internal angles of each polygon of a shapefile, and return them as follows:

 

• either concatenated on a new field;
  
• or on a table;
  
• or as a new points shapefile, in which each point corresponds to a vertex of each of the original polygons, with an attribute for "angle".
  
  Whichever way I get the values for the angles is fine.
