Parallelogram jklm is shown on the coordinate plane below:

parallelogram jklm with ordered pairs at j negative 6, 2, at k negative 4, 6, at l negative 3, 3, at m negative 5, negative 1.

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?

The coordinates of end points of the side congruent to JM i.e J'M' are J'(-2,-6) & M'(-1,5).

Step-by-step explanation:

Given the coordinates of parallelogram JKLM

J(-6,2) , K(-4,6), L(-3,3), M(-5,-1)

Now, the parallelogram JKLM is rotated 270° clockwise around the origin, then the coordinates after rotation about 270° changes to

(x,y) → (y,-x)

Hence, the coordinates of the endpoints of the side congruent to side JM are

J(-6,2) →  J'(-2,-6)

M(-5,-1) → M'(-1,5)

answer: .64
