Question

PLEASE I NEED HELP ASAP THIS IS DUE Rotate XYZ 270 degrees about the origin (0’0) 

Answer 1

step one:

X(-3, 3) , Y(-7,5), Z(-3, 7)

change sign of vector but since it zero no need.

now add it with vector (0,0)

X(-3, 3) > X(-3, 3)

Y(-7,5) > Y(-7,5)

Z(-3, 7) > Z(-3, 7)

now apply rules.

270 about the origin is (x,y)→(y,−x)

X(-3, 3) → x(3,-3)

Y(-7,5)→ Y(5,-7)

z(-3,7)→ Z(7,-3)

Now, add 0 with it

same coordinates. :D

So it is the same! as the one u plotted
