The vertices of triangle IJK have coordinates I(−5, −2), J(−5, −4), and K(−4, −4).

Which coordinates are the coordinates of the vertices of triangle IꞌJꞌKꞌ when triangle IJK is rotated 180° clockwise around the origin?



A.
Iꞌ(5, 2), Jꞌ(5, 4), Kꞌ(4, 4)

B.
Iꞌ(−2, 5), Jꞌ(−4, 5), Kꞌ(−4, 4)

C.
Iꞌ(2, −5), Jꞌ(4, −5), Kꞌ(4, −4)

D.
Iꞌ(−5, 2), Jꞌ(−5, 4), Kꞌ(−4, 4)

Answer 1

D?

Answer 2

D is not the right ans. sorry!

easiest way to solve is to pick one point (I, J or K) and rotate it 180deg. to see where it ends up.

Answer 3

Ok so C....
