You can put this solution on YOUR website! Find the number of sides of a polygon if the sum of the measures of its interior angles is twice the sum of measures of its exterior angle.
-----------------
The sum of exterior angles = 360 for all polygons.
--> 720 for internal angles
-----------
720 = 180*(n-2)
n = 6 sides
