@AMQ

AMQ:

We're supposed to match the different types of rotations with the rules, correct?

trueangel12312:

I guess

Arcadiouse:

Desmos, is a really good website for graphing. It would help you a lot.

trueangel12312:

I know but I would rather someone walk me through how to solve it

AMQ:

@Arcadiouse Apparently, that is not relevant to the question at hand. Please only post relevant comments. Thanks. :)

AMQ:

@trueangel12312 Let's match the rotations we worked on in the past questions. Do you remember the rules for 180 degrees and 90 degrees clockwise?

trueangel12312:

Um was I not right x.x

trueangel12312:

90 degrees= (x,-y) right?

trueangel12312:

Ooor (y,-x)

AMQ:

Yeah, (y,-x)

AMQ:

What about 180 degrees?

trueangel12312:

For 180 degrees if it is already negative you would make it positive but if it is positive it would be negative so (x,y)

trueangel12312:

@AMQ Am I right?

AMQ:

umm

AMQ:

You don't change the rule, you change the values if you have to. The rule is (-x,-y) for 180 degree rotations.

trueangel12312:

So is that clockwise?

AMQ:

180 degrees is the same for clockwise and counterclockwise

trueangel12312:

OHHH OK I GET IT! Thanks now one more I don't get this one

trueangel12312:

270 degrees??

AMQ:

If I'm correct, I believe the rules for 270 degrees are the same for 90, but are switched around a bit. lemme check

AMQ:

Hmm, I'm pretty sure that 270 degrees for both clockwise and counterclockwise is (-y,x). That's the same for 90 degrees counterclockwise.

trueangel12312:

Oh okay thanks!

trueangel12312:

Now I have to graph a ton of things x.x
