Question

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?

Answer 1

woah

Answer 2

A.
Parallelogram JKLM was reflected across the y-axis and then dilated by a scale factor of 1/8 .

B.
Parallelogram JKLM was dilated by a scale factor of 1/4 and then translated 1 unit right and 2 units down.

C.
Parallelogram JKLM was rotated 270° clockwise and then dilated by a scale factor of 1/4 .

D.
Parallelogram JKLM was dilated by a scale factor of 1/8 and then translated 4 units to the right.

Answer 3

well.what do u think?

Answer 4

C

Answer 5

@chosenmatt

Answer 6

good job

Answer 7

C is the wrong answer.

Answer 8

then what is it?

Answer 9

D

Multiply the coordinates for points JKLM by 1/8, and will get the coordinates for J'K'L'M'. For example, the J coordinate is (-8,16). So multiply 8 times 1/8 and you get 1. Multiply 16 by 1/8 and you get 2. So J' is (-1,2)

Next move the x coordinates for J'K'L'M' to the right 4 units and you will get J"K"L"M" So for J' you add 4 to the x coordinate. So -1+4=3 So J" coordinate is (3,2)
