One question, see below

Answer 1

equal, last time i told you, when the angles converge at a point, the sum is always 360, whatsoeva-gon may it be, even a 110-gon and a pentagon have equal ext angle sum. Remember: the sum of exterior angles of a given whatsoeva-gon (:P) is 360. And constant. Hope you don't mind the informal way.

Answer 2

Formula for each angle of a n-gon is : (n-2)*180deg/n -----> Gen formula for all polygon.....

for oct : (8-2)*180/8 = 135 deg
