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.
