The figure shows two triangles on a coordinate grid:
A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A triangle ABC is shown with vertex A on ordered pair negative 4, negative 1, vertex B on ordered pair negative 3, negative 1 and vertex C on ordered pair negative 4, negative 4. Another triangle A prime B prime C prime is shown with vertex A prime on ordered pair negative 1, 1, vertex B prime on ordered pair negative 2, 1, and vertex C prime on ordered pair negative 1, 4.
What set of transformations is performed on triangle ABC to form triangle A′B′C′? (4 points)
A translation 5 units up followed by a 180-degree counterclockwise rotation about the origin
A translation 5 units up followed by a 270-degree counterclockwise rotation about the origin
A 180-degree counterclockwise rotation about the origin followed by a translation 5 units to the left
A 270-degree counterclockwise rotation about the origin followed by a translation 5 units to the left
