mallory cameron
geometry rotations explained (90,180,270,360)
working with following transformation on △lmk: r180
l(2,6) → l(-2,-6)
m(8,8) → m( )
k(7,4) → k( )
multiple - choice question
what are the new coordinates for m?
(8,8)
(-8,-8)
(8,-8)

Explanation:

Step1: Recall rotation rule

For a 180 - degree rotation about the origin, the rule is $(x,y)\to(-x,-y)$.

Step2: Apply rule to point M

The original coordinates of M are $(8,8)$. Using the rule $(x,y)\to(-x,-y)$, we get $x = 8,y = 8$, then $-x=-8$ and $-y = - 8$.

Answer:

(-8,-8)
