Answer:
octagon
An interior angle of a regular polygon has a measure of 135°, it is an octagon.
Step-by-step explanation:
Answer:
octagon
Step-by-step explanation:
Here are two ways to solve this:
1) The total of the interior angles of a n-gon is given by
(n-2)* 180
then each angle is (n-2)(180)/n
so (n-2)(180)/n = 135
n = 8 so it is an octagon
2) The interior and exterior angles sum to 180
so the exterior angle is 45
the sum of all of the exterior angles = 360
45 n = 360
n = 8 octagon
