Let:
n - be the number of sides
n = 12
*No. of diagonals
=
=
=
=54 diagonals
------------
*Sum of Interior Angles
=
=
=
= 1800 degrees
----------
*Sum of Exterior Angles
=
=
= 30 degrees is an example and the sum is 360 degrees
-----------
*Example of Interior
= Sum of Interior Angles/n
=
= 150 degrees
