Answer 9

"rotates around its center" 72 I believe, else 180, so your choice

is that it?

Answer 12

i can't tell for sure. but rotating a figure 180 degrees would be like the following
(x,y) --> (-x, -y) so it would change and not get the same position of the grid However if you rotate it 2 times by 180 degrees you'd get the same shape on the same coordinates,

Answer 13

thank you but can the figure rotate any other degrees besides 180 and 72?

Answer 14

complete rotation would be 360 I believe, but 360 isnt an option. so rotating half way is 180, is that true?

Answer 15

it says select all the answers that are correct lol

Answer 16

i am still thinking i won't leave till i get the right answer. im checking my notebook hang on

Answer 17

Luny i don't believe 180 degrees is correct because it would change the coordinates else where.

Answer 18

okay sorry um 36 is half 72 would that be an answer?

Answer 19

72 x 5 = 360. So it is part of the answer I believe, yes

Answer 20
