Answer 2

Sum of Interior Angles = (n-2) × 180°

Answer 3

wait

Answer 4

lol wut?

Answer 5

Answer 13

@hedyeh99 plz halp

Answer 14

an octagon has 8 sides

Answer 15

Everything else look good though?

Answer 16

for the formula part of 180(n-2) you plug in 8 for n to find the sum of interior angles

Answer 17

the reason it is an octagon, which I just now figured out is for this "theorem"
