Question 1091456
How many sides are there in a polygon if the sum of the interior angles is 
a) equal to the sum of the exterior angles = 360 degs
4
==========
b) double the sum of the exterior angles = 720 degs
Sum = 180*(n-2) = 720
n-2 = 4
n = 6
---------------
c) 5 times the sum of the exterior angles?
----------------
Do it like b above.
