Question

please help, will medal! easy question, just check

Answer 1

I think A?

Answer 2

close. you can rotate the figure 90 to match original figure

Answer 3

Ok, so B?

Answer 4

umm i dont think so

Answer 5

one rotation is 360 degrees

Answer 6

look it up

Answer 7

I understand that one rotation is 360 degrees

Answer 8

so if it does a rotaion and it looks the exact same then it has rotational symetry

Answer 9

but i might be wrong

Answer 10

Don't all shapes look the same after one rotation

Answer 11

OMG

Answer 12

I agree with @nikato but for some reason 90 degrees isn't listed

Answer 13

...............

Answer 14

i feel stupid

Answer 15

ii shouldnt be helping people

Answer 16

@fantageplayer haha I'm pretty sure its B because 90 degrees falls under less than 180

Answer 17

i will go educate myself untill i am worthy then i shall come back to this website

Answer 18

fairwell

Answer 19

It's ok everyone messes up its all good

Answer 20

WAIT

Answer 21

a has to be correct

Answer 22

it says 360 or less

Answer 23

wait im still wrong

Answer 24

fairwell oncemore

Answer 25

But if it rotates over 180 it won't be symmetrical

Answer 26

it can be A or B
the figure will still look the same if you rotate it 90, 270, or 360

Answer 27

Ok thanks

Answer 28

this problem is just badly worded

A is true but you can rotate any figure 360 degrees to make it match up with itself. The figure wouldn't have to have rotational symmetry at all. So while choice A is true, I wouldn't go with it

I'd go with choice B because if you can rotate a figure 180 degrees and have it match up with itself, then it has rotational symmetry

Answer 29

Thanks!
