Question

1 True or False: A figure in a plane has rotational symmetry if the figure can be mapped onto itself by a rotation of 180 degrees or less.
2 True or False: A rectangle has rotational symmetry.
3 True or False: A trapezoid has rotational symmetry.
4 True or False: An octagon has rotational symmetry

Answer 1

false

Answer 2

false bc its 21

Answer 3

true because its 21

Answer 4

draw a rectangle

Answer 5

ok

Answer 6

actually first of all is #1 true or false?

Answer 7

false

Answer 8

where do you get that definition? the definition of rotational symmetry?

Answer 9

An object has rotational symmetry if there is a center point around which the object is turned (rotated) a certain number of degrees and the object looks the same. The number of positions in which the object looks exactly the same is called the order of the symmetry.

Answer 10

im not very smart😂

Answer 11

lol wut? why u say that?

Answer 12

im not good at math.

Answer 13

so to me #1 is false, so i agree with you

Answer 14

actually nvm i think its true

Answer 15

based on the assumption that #1 is true, what do you think #2, #3, and #4 are?

Answer 16

true, false, true

Answer 17

correct, and how many degrees would you have to rotate a rectangle to have it map onto itself?

Answer 18

assuming the rectangle has different length and width

Answer 19

180.

Answer 20

i believe

Answer 21

correct and what about an octagon?

Answer 22

it can.

Answer 23

how many degrees until it maps onto itself?

Answer 24

180

Answer 25

no its less

Answer 26

so true?

Answer 27

it is true, as you said above, but im just trying to see if you understand

Answer 28

why

Answer 29
