<PRE><B>Question 1000853</B>
Find the measure of each 
(a) interior angle of a regular octagon
The octagon has eight sides.
Sum of the interior angles = (8-2)180 = 6^180 degrees
---
Each of the interior angles is (6*180)/8) = 135 degrees
----------------------------------------- 

(b) reflex interior angle of the octagon.
The reflex interior angle is the corresponding exterior angle.
They are supplementary.
Ans: 180-135 = 45 degrees
