12.1.4 Compositions of Transformations - Practice
1. Translate R ( − 3, 4) along the vector 〈 7, − 6 〉 and then the vector 〈−1, 3〉.
2. △ JKL has vertices J ( − 3, 5), K ( − 1, 0) and L (8, − 4). Translate △ JKL along vector 〈−4, 7〉 and reflect it across the x -axis.
3. △ MNO has vertices M (8, − 2), N ( − 15, − 20) and O ( − 14, 19). Translate △ MNO along vector 〈7, −2〉 and reflect it across the y -axis.
4. Translate D ( − 5, 4) along vector 〈6, −8〉 and reflect it across the y -axis.
5. △ FGH has vertices F (4, − 12), G ( − 8, − 7), and H ( − 5, 9). Reflect △ FGH across the line y = x and rotate it of 90 ° about the origin.
6. Which of the following shows the two lines of reflection that produce an equivalent transformation of the translation ABCD → A ′ B ′ C ′ D ′? ○
