~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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.
