What is the order of rotation of this figure?
The order of rotation is the number of times that you can rotate the figure and it will match up. For example, the order of rotation of an equilateral triangle is 3 because you can rotate the triangle about it's center 3 times and it will match up with itself every time. In this case, how many times can you rotate the given figure to make it match up with itself (keep in mind that you can't go past 360 degrees)?
Another example, the order of rotation of any square is 4 because you can rotate a square about the center 4 times and it will match up with itself.
im still kind of confused
think of it like a wheel
we can rotate this wheel, but it will change when we do so correct?
with me so far?
yes
alright, so we can rotate it and it will change...but...there are points where we will rotate this and it will revert back to it's original image, agree?
right i agree
how many times does it revert back to the original if we rotate it 360 degrees?
2 times i think
pretty close, but you can actually do it 4 times
ohh okay
it might be hard to see, so maybe drawing it (or printing it out) and actually physically rotating it might help
i will actually do that thats a good idea
yes makes me wish there was an interactive portion to this problem so you can actually do just that, but oh well
ya lol so the answwer is 4?
yes you got it
yes i understand this one much more
that's great :)
