Read each question carefully and follow the instructions to perform reflections on the coordinate plane. Show all your work.
1. Reflect the point A(3, -2) across the x-axis. What are the coordinates of A'?
2. When a point (x, y) is reflected across the y-axis, the new coordinates are ( , ).
3. What are the coordinates of the image of point B(-5, 4) after a reflection across the line y = x?
B'(-5, -4)
B'(5, 4)
B'(4, -5)
B'(-4, 5)
4. Triangle DEF has vertices D(1, 1), E(4, 2), and F(2, 5). Reflect triangle DEF across the x-axis. List the coordinates of the reflected triangle D'E'F'.
5. A reflection is an isometry, meaning it preserves distance and angle measure.
True
False
6. Find the image of the point C(6, -3) after a reflection across the line y = -x. What are the coordinates of C'?
