You can put this solution on YOUR website! what is the number of sides of a regular polygon whose interior angles each measure 135 degrees?
---
Fact: The sum of the exterior angles is 360 degrees.
----
If an interior is 135 the corresponding exterior is 180-135 = 45 degrees
--
So each of the exteriors is 45 degrees.
---
# of exterior angles = 360/45 = 8
---
# of sides = # of exterior angles = 8
