Read each question carefully and follow the instructions to perform the reflections. Show all your work for full credit.

1. Reflect the triangle with vertices A(1, 2), B(4, 5), and C(3, 1) across the x-axis. State the coordinates of the reflected triangle A'B'C'.

2. A reflection is a transformation that acts like a image. The original figure is called the , and the reflected figure is called the .

3. Reflect the quadrilateral with vertices P(-2, 3), Q(1, 4), R(3, 1), and S(-1, -2) across the y-axis. State the coordinates of the reflected quadrilateral P'Q'R'S'.

4. Which of the following lines would result in the image (2, -3) when the point (-2, -3) is reflected?

x-axis

y-axis

y = x

y = -x

5. A reflection changes the size of a geometric figure.

True

False

6. Reflect the point (5, -2) across the line y = x. What are the coordinates of the reflected point?
