Question

Help and get a medal and a fan request for the right answer/// Does the figure have rotational symmetry? if it does fined the angle of rotation
A) yes 30*
B) yes 60*
C) yes 72*
D) No

Answer 1

just to be clear it's a star lol

Answer 2

you can rotate this star 5 times and it will match up with itself every time

so the angle of rotation is 360/5 = 72 degrees

Answer 3

oh ok

Answer 4

kool

Answer 5

so its yes 72

Answer 6

another example: if you had a square, you can rotate that 4 times (until you have fully rotated a full revolution) and the rotated figure will match up with the original figure each of the 4 times

so the angle of rotation of a square is 360/40 = 90 degrees

ie each 90 degree rotation produces the same original figure...nothing has changed

Answer 7

oops meant to say 360/4 = 90 degrees, but you get the idea

Answer 8

correct, choice C

Answer 9

ok thanks you still want that medal and fan request
