Approximately how many degrees are in the measure of an interior angle of a regular eight sided polygon?
----------
The sum of interior angles = 180*(n-2) = 180*6 = 1080 degs
1080/8 = 135 degs
-----------------------
The exterior angles for ALL regular polygons = 360/n, n = # of sides
360/8 = 45 degs
Int = 180 - Ext = 135 degs
--------------
It's not approximate, it's exact.
