Recognise Reflective Symmetry

In this activity, we will be learning to reflect patterns in a mirror line.

Let's look at some examples together. 

Look at this diagram:

The dotted line is a mirror line, so when we reflect the yellow and the red squares we get the following diagram.

This arrangement has one line of reflective symmetry.

The following arrangements have two lines of reflective symmetry:

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