Question

Parallelogram JKLM is shown on the coordinate plane below.



If parallelogram JKLM is rotated 270° counterclockwise around the origin, what are the coordinates of the endpoints of the side congruent to side KL in the image parallelogram?
Answer
K’(-6, -4); L’(-3, -3)
K’(-4, -6); L’(3, -3)
K’(-4, 6); L’(-3, -3)
K’(6, 4); L’(3, 3)

Answer 1

Hint: To rotate any point 270 degrees counter clockwise around the origin, you use this rule

(x,y) ---> (y,-x)
