## 1. Click the box to illustrate a y-axis reflection.

Study the set of ordered pairs from the original figure and compare them to the set of ordered pairs from the new figure. What happens to the ordered pairs when you reflect a figure across the y-axis.

## 2. Write a mapping notation rule for reflecting across the y-axis

(x, y)

## 3. Click the box to illustrate a x-axis reflection.

Study the set of ordered pairs from the original figure and compare them to the set of ordered pairs from the new figure. What happens to the ordered pairs when you reflect a figure across the x-axis.

## 4. Write a mapping notation rule for reflecting across the x-axis

(x, y)

## 5. Create your own figure by moving the vertices around.

Create a figure that is in the 1st and 2nd quadrants (crosses the y-axis). Describe what happens to the original figure and new figure when you use a y-axis reflection.
