Unit 5 Post Test Review Sheet
Answer the following questions in your notebook to best prepare
for your upcoming Unit 5 Post Test. You must show all work to
receive credit. 1) If this triangle was reflected over the y-axis
to form triangle
X’Y’Z’, what would be the coordinates of vertex Z’?
2) What set of coordinates will provide the vertices for a 900
clockwise rotation of triangle JKL?
3) What set of coordinates will provide the vertices for the
translation
of triangle KLM 4 units down?
4) What set of coordinates will provide the vertices for a 1800
rotation of triangle ABC?
5) Triangle ABC is reflected over the y-axis to create triangle
A’B’C’.
Which side is congruent to 𝐴𝐶?
6) Triangle ABC is reflected across the y-axis to obtain A’B’C’
as shown below.
7) In the graph below, figure C represents the preimage and
figure T represents the image.
Determine if the following images are congruent or similar. Then
describe the sequence of transformations that transforms C to
T.
8) Describe a sequence of transformations that transforms ABC to
DEF.
9) Write a sequence of transformations on triangle ABC that is
congruent to triangle ABC.
10) Which sequence of transformations can map ABC onto DEF?
Determine if the two figures are congruent or similar. If
congruent, complete the following:
a) AB = _____ b) BC = _____ c) AC = _____
11) Triangle A’B’C’ is the image of triangle ABC after a
dilation. The center of dilation is the origin. What is the scale
factor of the dilation?
12) Quadrilateral M’A’T’H’ is the image of quadrilateral MATH
after the transformation shown below. What was the
transformation?

as shown below. What best describes Magda’s transformation?
14) The image of point A after a dilation of 4 is (4,20). What
was the original location of point A?
15) The figure MNOP shown below is dilated by a scale factor of
!! and
then rotated counterclockwise about the origin through 900 to
obtain the figure M’N’O’P’. What are the coordinates of the new
quadrilateral M’N’O’P’?
16) Triangle DEF is obtained by transforming triangle ABC as
shown below. Determine the sequence that occurs between triangle
ABC and DEF, and
17) The figure ABCD is transformed to obtain the figure EFGH, as
shown below. Determine if the following figures are congruent or
similar, and then describe the sequence of transformations that
occurs from ABCD to EFGH.
18) What sequence of translations, rotations, and/or dilations
transforms figure A into figure B?
19) Triangle DEF is the result of a dilation of triangle ABC
with the center of dilation at the origin and a scale factor of
!
!. Write a
proportion that shows equal ratios with sides.
20) Congruent polygons A and B are shown on the coordinate grid
below. Describe a sequence of transformations on polygon A that
would result in polygon B.
