Answer: reflection, then translation
Step-by-step explanation:
"Triangles P Q R and S T U are shown. Triangle P Q R is reflected across Q R and then is shifted up and to the right to form triangle S T U."
While I do not have a picture of the triangles, according to the description given the answer is reflection, then translation. Reflected means a reflection, and shifted up and to the right is known as a translation.
