Lesson 2 Homework Practice Reflections 1. Graph ∆ABC with vertices A(2, 2), B(5, 4),and C(5, 1) and its reflection over the x-axis. Then find the coordinates of the reflected image. 2. Graph square ABCD with vertices A(–1, 2), B(2, –1), C(5, 2), and D(2, 5) and its reflection over the y-axis. Then find the coordinates of the reflected image. The coordinates of a point and its image after a reflection are given. Describe the reflection as over the x-axis or 3. B(1, –2) → Bʹ(1, 2) 4. J(–3, 5) → Jʹ(–3, –5) 5. W(–7, –4) → Wʹ(7, –4) For Exercises 6–9, use the following information. Triangle XYZ has vertices X(4, 2), Y(4, 4), and Z(0, 2). 6. What are the coordinates of the image of point X after a reflection over the y-axis? 7. What are the coordinates of the image of point Y after a reflection over the y-axis? 8. What are the coordinates of the image of point Z after a reflection over the y-axis? 9. Graph triangle XYZ and its image after a reflection over the x-axis.
