I think that the angles of the polygon would not change since there isn't a change of the shape, rather it position and rotation. The sum of each internal angle is found using S = 180(n-2), so
S = 180(5-2)
S = 180(3)
S = 540
540 / 5 = 108 degrees.
Therefore, all angles in the polygon is 108 degrees. I think this is what you meant right?
