Parallelogram JKLM has coordinates J(−8, 16) , K(8, 16) , L(16, −8) , and M(0, −8) . Parallelogram J'K'L'M' has coordinates J′(−1, 2) , K'(1, 2) , L′(2, −1) , and M′(0, −1) . Parallelogram J"K"L"M" has coordinates J"(3, 2), K"(5, 2) , L″(6, −1) , and M″(4, −1) . Which transformations describe why parallelograms JKLM and J"K"L"M" are similar? Parallelogram JKLM was dilated by a scale factor of 1/8 and then translated 4 units to the right. Parallelogram JKLM was dilated by a scale factor of 1/4 and then translated 1 unit right and 2 units down. Parallelogram JKLM was rotated 270° clockwise and then dilated by a scale factor of 1/4 . Parallelogram JKLM was reflected across the y-axis and then dilated by a scale factor of 1/8 .
Sorry i am late, but my answer is for those taking the quiz now,
The correct answer is Parallelogram JKLM was dilated by a scale factor of 1/8 and then translated 4 units to the right.
:) Hope this help xd
Parallelogram JKLM was rotated 270° clockwise and then dilated by a scale factor of 1/8.
From the distance formula
JK = 16
KL = \(2\sqrt{165}\)
LM = 16
MJ = \(2\sqrt{165}\)
Similarly,
J"K" = 2
K"L" = \(\sqrt{10}\)
L"M"=2
M"J"= \(\sqrt{10}\)
If a parallelogram is reflected about the y-axis then the Y-coordinate of each edge will be unchanged while the X-coordinate will become -X.
so coordinates of parallelogram JKLM after reflection about y-axis will be
J≡(8,16)
K≡(-8,16)
L≡(-16,-8)
M≡(0,-8)
JK = 16
KL = \(2\sqrt{165}\)
LM=16
MJ = \(2\sqrt{165}\)
J"K"/JK = 2/16 = 1/8
it means JKLM was dilated by a factor of 1/8
Hence, Parallelogram JKLM was reflected about the y-axis and then dilated by a scale factor of 1/8.
