How can I rotate a figure to carry onto itself?

OpenStudy (anonymous):

OpenStudy (anonymous):

easy, rotate it by he calculation of 56 x 78 and you rotate it

OpenStudy (anonymous):

Why 56 and 78?

OpenStudy (anonymous):

Well do you know x = y

OpenStudy (anonymous):

and y = x?

OpenStudy (anonymous):

yeah had this question before. Got it right.

OpenStudy (anonymous):

I know that x=y and y=x.

OpenStudy (anonymous):

Rotate 180°, reflect over the x-axis, reflect over the line y=x Reflect over the y-axis, reflect over the x-axis, rotate 180° Rotate 180°, reflect over the y-axis, reflect over the line y=x Reflect over the x-axis, rotate 180°, reflect over the x-axis

OpenStudy (anonymous):

So it's either a or c?

OpenStudy (anonymous):

yeah

OpenStudy (anonymous):

trust me, whenever you need help just ask me

OpenStudy (anonymous):

So I rotate it first?

OpenStudy (anonymous):

okay look

OpenStudy (anonymous):

|dw:1418674972553:dw|

OpenStudy (anonymous):

do you know what this means?

OpenStudy (anonymous):

yeah, I had this question before.

OpenStudy (anonymous):

That is the line of rotation right?

OpenStudy (anonymous):

what

OpenStudy (anonymous):

well it means y = x

OpenStudy (anonymous):

yes it is the line of rotation. If it is wrong, then that is dumb because I had this exact question in my test 9 times.

OpenStudy (anonymous):

Sorry, I'm really bad at rotations.

OpenStudy (anonymous):

it's okay

OpenStudy (anonymous):

What do you think the answer is?

OpenStudy (anonymous):

I think it is A

OpenStudy (anonymous):

yeah, it is a

OpenStudy (anonymous):

The answer has always been A.

OpenStudy (anonymous):

Well no, ill just give ya the answer its B.

OpenStudy (anonymous):

Thank you so much! I have to redo it because I got a 30 on it. :/

OpenStudy (anonymous):

can someone make me have a fan, a medal and a best answer.

OpenStudy (anonymous):

Oh. Why?

OpenStudy (anonymous):

Its not A. Its B.

OpenStudy (anonymous):

What was the answer @jadaaaa

OpenStudy (anonymous):

I need to have something because I am new. please. I preety much gave you the answer.

OpenStudy (anonymous):

Can someone make me have best answer

OpenStudy (anonymous):

I haven't finished it yet, I really want to get the right answer.

OpenStudy (anonymous):

WHta do you mean you have not finished yet

OpenStudy (anonymous):

Thank you so much for giving me a medal. I will give you best response.

OpenStudy (anonymous):

lovielove, your answer A. is incorrect… the correct answer is B.

OpenStudy (anonymous):

I gave you best response

OpenStudy (anonymous):

The test. I still have like 4 questions left.

OpenStudy (anonymous):

oh what is the question

OpenStudy (anonymous):

Thanks.

OpenStudy (anonymous):

@Pico33 why is it B?

OpenStudy (anonymous):

what is the questions in the test

OpenStudy (anonymous):

Triangles DEF and D'E'F' are shown on the coordinate plane below: What rotation was applied to triangle DEF to create triangle D'E'F'? If rectangle ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie? What set of transformations could be applied to rectangle ABCD to create A'B'C'D'? If parallelogram JKLM is rotated 270° clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side KL in the image parallelogram?

OpenStudy (anonymous):

1. rotation 360 2. Point A woud lie in 67 degrees

OpenStudy (anonymous):

Those aren't my answer choices though.

OpenStudy (anonymous):

ohh, well that is wierd

OpenStudy (anonymous):

A was wrong.
