1) Describe two distinct rigid transformations that would map figure 1 onto figure 2.
y
1
2
O
x
A reflection across the y-axis or a translation 5 units to the right.
2) Can you use the same two rigid transformations from #1 in order to map ABCD onto WXYZ?
y
A
B X
W
O
D
C Y
x
Z
A reflection across the y-axis will map ABCD onto WXYZ, but a translation 5 units to the right will not map the
corresponding vertices onto each other.

3) ABC is reflected over the x-axis, and then reflected over the y-axis to form the image whose sides are
represented by x, y, and z. Identify the corresponding side lengths for the pre-image and image.

y
z
The side with length z corresponds to AB , the side with length x corresponds to AC , and the side with length y
corresponds to BC .
