#### Worksheet Overview

In this activity, we will learn to identify shapes that have been reflected in a mirror line.

When we reflect a shape, it appears flipped, like a mirror image.

The mirror line is often marked using a dotted or dashed line.

Look at the following L-shapes drawn on x and y-coordinate axes.

When we reflect a shape in a mirror line, we reflect each corner in turn.

This is done by moving each point directly to the mirror line and then the same distance beyond.

Shape A and Shape B are reflections of each other in this vertical mirror line.

Let's try an example together.

Example

Is the mirror line used to reflect shape A to shape B, vertical or horizontal?

In the following example, the mirror line is horizontal.

The same technique is used to reflect the shape.

Now it's time for you to have a go at some questions.
