so like a first help B will have coordinates (-1,-5)
ok ?
OpenStudy (anonymous):
c (-4,5) a (0) b (5,1) I'm horrible at this...
OpenStudy (anonymous):
Oh okay.
jhonyy9 (jhonyy9):
so can you continue ?
OpenStudy (anonymous):
I don't think I can do it by myself.

OpenStudy (anonymous):
Yeah,
OpenStudy (anonymous):
It would stay where it is.
jhonyy9 (jhonyy9):
so then C coordinates will be (4,-5)

jhonyy9 (jhonyy9):
but do you understand it how and why ?
OpenStudy (anonymous):
I understand that part.
jhonyy9 (jhonyy9):
so try rotating this triangle about origin 180 degree and will get the right answer
OpenStudy (anonymous):
I'm probably wrong... but I'm thinking B?
jhonyy9 (jhonyy9):
ahhh ! there are choises ?

OpenStudy (anonymous):
lol
OpenStudy (anonymous):
Files labeled a b c and d
jhonyy9 (jhonyy9):
C is right sure
check it please in text of exercise wrote 180 degree
jhonyy9 (jhonyy9):
so what mean the point B will be rotated about origin two quadrants
yes ?

jhonyy9 (jhonyy9):
one quadrant mean 90 degree then two will be 180 degree
ok ?
OpenStudy (anonymous):
Oh sorry. I should be specific. I meant that, I'm thinking Option B. is correct.
jhonyy9 (jhonyy9):
no ! C will be correct
ok ?
OpenStudy (anonymous):
Oh! Okay, sorry. Thank you for your patience. =)
jhonyy9 (jhonyy9):
