# Reflections

Exploring Reflections

## Instructions

- Move the "mirror line", which we call the

**Line of Reflection**in our class, to the appropriate location to answer the questions below.## 1. Line of Reflection: Y-axis

What happens to the coordinates of the vertices of the shape after a reflection about the y-axis?

## 2. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.

Reflection about the y-axis: (x, y)

## 3. Line of Reflection: X-axis

What happens to the coordinates of the vertices of the shape after a reflection about the x-axis?

## 4. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.

Reflection about the x-axis: (x, y)

## 5. Line of Reflection: y = x

What happens to the coordinates of the vertices of the shape after a reflection about the line y=x?

## 6. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.

Reflection about the line y = x. (x, y)

## 7. Line of Reflection: y = -x

What happens to the coordinates of the vertices of the shape after a reflection about the line y=-x?

## 8. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.

Reflection about the line y = -x. (x, y)
