Answer:

octagon

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
