Read each question carefully and follow the instructions to complete the reflections. Show all your work on the coordinate planes provided.
1. What is a reflection in geometry?
2. When a point (x, y) is reflected over the x-axis, its new coordinates are (x, ).
3. When a point (x, y) is reflected over the y-axis, its new coordinates are ( , y).
4. When a point (x, y) is reflected over the line y = x, its new coordinates are ( , ).
5. Plot the point A(3, 2). Then, reflect point A over the x-axis to create A'. What are the coordinates of A'?
A' = ( , )
6. Plot the triangle with vertices B(-4, 1), C(-1, 1), and D(-2, 4). Then, reflect triangle BCD over the y-axis to create B'C'D'. List the coordinates of the reflected vertices.
B' = ( , )
C' = ( , )
D' = ( , )
7. A reflection changes the size of a figure.
True
False
8. The line of reflection is always equidistant from any point and its image.
True
False
