Question

The figure below shows two triangles on the coordinate grid:

What set of transformations is performed on triangle ABC to form triangle A′B′C′? (5 points)

Group of answer choices

A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin

A translation 5 units down, followed by a 270-degree counterclockwise rotation about the origin

A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down

A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units down

Answer 1

• Option A

Explanation:

A translation 5 units down, followed by a 180-degree counterclockwise rotation about the origin

• Correct

A translation 5 units down, followed by a 270-degree counterclockwise rotation about the origin

• Incorrect. It would work with 180-degree rotation.

A 180-degree counterclockwise rotation about the origin, followed by a translation 5 units down

• Incorrect. It would work with the translation 5 units up.

A 270-degree counterclockwise rotation about the origin, followed by a translation 5 units down

• Incorrect.
