Triangle DEF is translated down 9 units and then reflected across the y axis to form Triangle xyz. Match the sides that are equal in length to each other.

• x

• EF

• y

• DF

• z

• DE

Triangle GHI is rotated 90 degrees colock-wise and then reflected across the y axis to form Triangle xyz. Match the sides that are equal in length to each other.

• z

• GH

• y

• IH

• x

• GI

HINT: Draw the original parallelogram. Remember that the only thing that changes the size of a shape is dilation.
