Question

The vertices of / are k(–1, 4), l(8, 3), and m(4, –1). / is rotated 270° counterclockwise about the origin to form /. what are the coordinates of the vertices of /?

Answer 1

K (4,1)
I (3,-8)
M (-1,-4)
do 180 counterclockwise first then do 90 counterclockwise to find 270 counterclockwise
( you can check it again)
