The figure below shows triangle PQR and some of its transformed images on a coordinate grid:

A coordinate plane is shown with five triangles. Triangle PQR has vertices 2 comma 1, 5 comma 1, and 2 comma 4. Triangle A has vertices negative 2 comma 1, negative 5 comma 1, and negative 5 comma 4. Triangle B has vertices negative 6 comma 1, negative 6 comma 4, and negative 9 comma 1. Triangle C has vertices negative 2 comma negative 1, negative 2 comma negative 4, negative 5 comma negative 4. Triangle D has vertices 2 comma negative 1, 5 comma negative 1, and 5 comma negative 4.

Which of the four triangles was formed by a translation of triangle PQR?

It should be a as all the other options are reflections or rotational transformations

The original triangle has the right angle in the lower-left corner. Any translation will, too,

Triangle A is the only one that matches that requirement.

_____

The other images are all some combination of rotation and reflection.
