Question

If parallelogram JKLM is rotated 270° clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side JM in the image parallelogram?

Answer 1

This question is poorly worded. Since this is a parallelogram, sides JM and KL are congruent in the original parallelogram. After the rotation, the images of both sides JM and KL will also be congruent to each other and both will be congruent to JM. Is the question asking about the image of JM or the image of KL after the rotation?

Answer 2

hm...

Answer 3

For a \(90^{\Large\textrm{o}}\) CCW rotation,
\[\begin{align}
P(x,y) &\rightarrow P'(-y,x) \\
J(-6,2) &\rightarrow J'(-2,-6) \\
M(-5,-1) &\rightarrow M'(1,-5)
\end{align}\]
