What set of reflections would carry hexagon ABCDEF onto itself?

OpenStudy (anonymous):

y=x, x-axis, y=x, y-axis x-axis, y=x, x-axis, y=x y-axis, x-axis, y-axis x-axis, y-axis, y-axis

OpenStudy (anonymous):

I don't know why this one is confusing me

ganeshie8 (ganeshie8):

sorry was afk...

OpenStudy (anonymous):

Sorry my connection went down @ganeshie8

ganeshie8 (ganeshie8):

to get to the same place, u need reflections that cancel each other

ganeshie8 (ganeshie8):

look at the given options, which option has the transformations that repeat exactly two times ?

OpenStudy (anonymous):

option B

ganeshie8 (ganeshie8):

yes, but that doesnt look right, let me think a bit :)

ganeshie8 (ganeshie8):

lets look at optionA

OpenStudy (anonymous):

Ok Take Your Time :)

ganeshie8 (ganeshie8):

y=x, x-axis, y=x, y-axis

ganeshie8 (ganeshie8):

say ur point is : (x, y)

ganeshie8 (ganeshie8):

after y=x : (x, y) -> (y, x) after x-axis : (y, x) -> (y, -x) after y=x : (y, -x) -> (-x, y) after y-axis : (-x, y) -> (x, y)

ganeshie8 (ganeshie8):

which is same as the point we have started with, so optionA is correct answer

ganeshie8 (ganeshie8):

if that makes any sense...

ganeshie8 (ganeshie8):

u can eliminate all other options by using the same logic

OpenStudy (anonymous):

This look familiar , I am on the verge to understanding it I just have to keep this in mind

ganeshie8 (ganeshie8):

good to hear :) we just need to systematically work every option and see !

OpenStudy (anonymous):

You're a wonderful help :)

ganeshie8 (ganeshie8):

you will find that oly optionA gives u the coordinates back watever u started wid

OpenStudy (anonymous):

That makes sense

ganeshie8 (ganeshie8):

aww no, you're wonderful at learning quickly :)

OpenStudy (anonymous):

Aw !! :D
