Triangle DEF is the image of triangle ABC after a sequence of transformations. transformations.

Two triangles are plotted on a graph. Triangle A B C has the following vertices. Vertex A is at negative 5 comma 4. Vertex B is at negative 5 comma 1. Vertex C is at negative 3 comma 1. Triangle D E F has the following vertices. Vertex E is at 5 comma negative 2. Vertex E is at 5 comma negative 4. Vertex F is at 3 comma negative 5.

Describe the transformation that occurs in each step, and be as specific as you can.
