~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Dear Abe, how are you? Hope everything is OK with you.


Regarding the sum of interior angles of a polygon, you can read on this subject from the lesson
Sum of interior angles of a polygon  in the site https:\\www.algebra.com.

Specifically for the sum of interior angles of a decagon (polygon with 10 sides and/or 10 vertices), 
it is equal to 1440�.  It is explained in the same lesson, Example 1.

I am looking forward to see you in the school tomorrow.
