Help!!! I will medal and fan!

OpenStudy (miss.rose):

Help!

OpenStudy (noseboy908):

Begin by finding the point they say to rotate around. What is it?

OpenStudy (miss.rose):

1,-1?

OpenStudy (noseboy908):

Yep. Which edge of the original image is that?

OpenStudy (miss.rose):

That is the opposite of what the said, which was -1,1. Is that correct?

OpenStudy (noseboy908):

You're right, it is (-1,1). So which corner is that?

OpenStudy (miss.rose):

The bottom left?

OpenStudy (noseboy908):

Not the bottom left, that would be (-2,1).

OpenStudy (miss.rose):

Then the bottom right?

OpenStudy (noseboy908):

Correct! Knowing that, imagine that you're holding down that corner of a rectangle, and turning it 90 degrees, or (in another way) 1/4th the way around a circle. Which image gets the closest to that?

OpenStudy (miss.rose):

The first one?

OpenStudy (noseboy908):

Correct!

OpenStudy (miss.rose):

I have one more, it is just like that one just a little different and by just like that one I mean the options/answers are the same. Here is the question:

OpenStudy (noseboy908):

This time we're working with the point (-2,1). Which point on the rectangle given is that?

OpenStudy (miss.rose):

What do you mean?

OpenStudy (noseboy908):

Sorry, which corner is that?

OpenStudy (miss.rose):

Oh... that would be the bottom left?

OpenStudy (miss.rose):

I am thinking the answer would be the second option/answer. Is that correct?

OpenStudy (noseboy908):

Correct! Now image (as before) that you are holding down that corner with your finger, and moving a rectangle 180 degrees, or half way around a circle. Understand how the image should look?

OpenStudy (miss.rose):

Should the answer be the second option/answer?

OpenStudy (noseboy908):

From the original choices? Yes.

OpenStudy (miss.rose):

Okay, thanks soooo much for your help! Just give me a minute to submit the test and I will come back on and give you what you promised. brb

OpenStudy (noseboy908):

Great, and take your time.

OpenStudy (miss.rose):

I am back, I gave you your medal, and I fanned you, I even wrote a testimonial for you. Again, thanks for all the help! Have a great rest of the day! Bye!
