Question

A triangle has vertices at A (−2, −2), B (−1, 1), and C (3, 2). Which of the following transformations produces an image with vertices A′ (−2, 2), B′ (−1, −1), and C′ (3, −2)?

Answer 1

The transformation that produces the image with vertices A′ (−2, 2), B′ (−1, −1), and C′ (3, −2) is a reflection across the line y = x.
