Answer:
Option B. Side YZ is the same length as side Y'X'.
Step-by-step explanation:
At first the image is for the given question
The true graph is the attached figure.
As shown at the attached figure.
XYZ is reflected across the y-axis and then translated down 6 units to form X'Y'Z'.
So, X' is the image of point X
Y' is the image of point Y
Z' is the image of point Z
And ΔXYZ ≅ ΔX'YΔ'Z'
And the corresponding length are congruent.
We will check the options:
A. X has the same measure as X'. ⇒ True
B. Side YZ is the same length as side Y'X'. ⇒ Wrong
Because YZ will be translated to Y'Z'
C. Z has the same measure as Z'. ⇒ True
D. Side XZ is the same length as side X'Z'. ⇒ True
So, The answer is option B. Side YZ is the same length as side Y'X'.
