OpenStudy (brooke..help00):

To draw---- Open word Go to review last box (start inking) you can draw what you need to with multiple color

OpenStudy (brooke..help00):

Please medal if helped*

OpenStudy (devonhoward15):

@3mar i need help with this

OpenStudy (devonhoward15):

brooke i dont see what your talking about

OpenStudy (3mar):

me too, I don't find "start inking".

OpenStudy (devonhoward15):

i cant figure out how to draw on word... i need to draw on that grid

OpenStudy (3mar):

Oh she is talking about "Windows tablet". not pc windows

OpenStudy (devonhoward15):

ok i figured out what i can do... i just need help with the coordinates

OpenStudy (devonhoward15):

is that right for the reflection?

OpenStudy (devonhoward15):

@3mar

OpenStudy (devonhoward15):

is that correct for a reflection over x-axis?

OpenStudy (devonhoward15):

anyone?

OpenStudy (devonhoward15):

@FaiqRaees

OpenStudy (devonhoward15):

@3mar please tell me if correct

OpenStudy (yourboydusty):

I think it is supposed to be the box next to the one with your points

OpenStudy (devonhoward15):

its a reflection across x-axis

OpenStudy (yourboydusty):

yes but it also says 180 degrees

OpenStudy (devonhoward15):

thats another part

OpenStudy (devonhoward15):

its two parts

OpenStudy (yourboydusty):

oh sorry as for the other part you are correct

OpenStudy (devonhoward15):

no worries mate

OpenStudy (yourboydusty):

your points are correct

OpenStudy (devonhoward15):

ok thanks... do you know how to rotate the original shape 180 degrees about its origin?

OpenStudy (devonhoward15):

i need help with part a @3mar

OpenStudy (yourboydusty):

yes it will be on the third square

OpenStudy (3mar):

Well, I am here.

OpenStudy (yourboydusty):

hey 3mar

OpenStudy (3mar):

Hello, friend!

OpenStudy (devonhoward15):

i need coordinates for part a and the letter it goes with

OpenStudy (yourboydusty):

How do you do been a while huh

OpenStudy (3mar):

For part a, 180 rotation cw or ccw?

OpenStudy (devonhoward15):

it says 180 about the origin

OpenStudy (3mar):

"yes it will be on the third square " no it will not

OpenStudy (3mar):

As we rotate it 180, it does not matter to cw or ccw. I just need you to pay attention, no more.

OpenStudy (devonhoward15):

it doesnt say cw or ccw... so guess it doesnt matter

OpenStudy (3mar):

Ok

OpenStudy (3mar):

The rule of the reflection of 180 ( cw or ccw) is \[(x,y)→(−x,−y)\]

OpenStudy (3mar):

Do this for the three points, and tell me

OpenStudy (devonhoward15):

ok working on it now

OpenStudy (3mar):

Nice!

OpenStudy (devonhoward15):

p(-1,1) q(-3,2) r(-3,4)... these are the final coordinates

OpenStudy (3mar):

p correct q correct r correct then can you draw the rotated triangle?

OpenStudy (devonhoward15):

yes i can

OpenStudy (3mar):

I have something for you!

OpenStudy (devonhoward15):

cool what is it?

OpenStudy (3mar):

Reflection across x-axis: (x, y) > (x, -y) Reflection across y-axis: (x,y) > (-x, y) Reflection over origin: (x,y) > (-x,-y) Reflection over line y = x: (x,y) > (y,x) Reflection over line y=-x: (x,y) > (-y,-x) This would help you...

OpenStudy (devonhoward15):

Thanks for the help... finally done with that paper

OpenStudy (3mar):

Thanks for Allah

OpenStudy (devonhoward15):

whats Allah?

OpenStudy (3mar):

Allah is the creator of me and you! Don't know who is your creator?
