Parallelogram JKLM has coordinates J (−8, 16), K (8, 16), L (16, −8), and M (0, −8). Parallelogram JꞌKꞌLꞌMꞌ has coordinates Jꞌ (−1, 2), Kꞌ (1, 2), Lꞌ (2, −1), and Mꞌ (0, −1). Parallelogram JꞌꞌKꞌꞌLꞌꞌMꞌꞌ has coordinates Jꞌꞌ (3, 2), Kꞌꞌ (5, 2), Lꞌꞌ (6, −1), and Mꞌꞌ (4, −1). Which transformations describe why parallelograms JKLM and JꞌꞌKꞌꞌLꞌꞌMꞌꞌ are similar? A. Parallelogram JKLM was reflected across the y-axis and then dilated by a scale factor of . B. Parallelogram JKLM was dilated by a scale factor of and then translated 1 unit right and 2 units down.

    See if you can find a rule to from J-> J' and from K -> K'.

    Did you notice that when the coordinates of J and K are divided by 8, you get the coordinates of J' and K'? What do you call that transformation?
