## Basics on the topicDifferent Types of Symmetry—Let's Practise!

Today we are identifying different types of symmetry with Razzi! This video contains examples to help you practise further and grow confident in this topic.

### TranscriptDifferent Types of Symmetry—Let's Practise!

Razzi says get these items ready because today we're going to practise identifying Different Types of Symmetry. It's time to begin! Does this object have reflective or rotational symmetry? Pause the video to work on the problem and press play when you are ready to see the solution! Since we can rotate the wheel around a central point HERE and it looks exactly the same, it has rotational symmetry. Did you also say rotational symmetry? Let's have a look at another object. Does this object have reflective or rotational symmetry? Pause the video to work on the problem and press play when you are ready to see the solution! Since one half of the object or shape reflects the other half, it has reflective symmetry. Did you also guess reflective symmetry? For the last problem, which one of these pictures is an example of rotational symmetry? Pause the video to work on the problem and press play when you are ready to see the solution! Since we can rotate the star around a central point HERE and it looks exactly the same, it has rotational symmetry. Razzi had so much fun practicing with you today! See you next time!

Would you like to apply the knowledge you’ve learnt? You can review and practice it with the tasks for the video Different Types of Symmetry—Let's Practise!.
• ### Select the correct definition.

Hints

This flower has reflective symmetry.

Rotational symmetry has a central point.

Solution

Reflective Symmetry: one half of the object reflects the other, shown on the left.

Rotational Symmetry: if the object is turned around a central point, it still looks the same, shown on the right.

• ### Does this picture have rotational symmetry?

Hints

This picture can be rotated around a central point and will still look the same.

This star is an example of an image with rotational symmetry.

Solution

The picture of the sun has rotational symmetry. yes

Since the sun can be rotated around the central point and always look the same, we know this is rotational symmetry.

• ### What form of symmetry do these shapes have?

Hints

Look at all of these shapes. Can they be rotated? Does one half reflect the other?

If a shape has rotational symmetry it can be turned around a central point and will still look the same. Are all of these shapes able to do that?

Can you find a line of symmetry on all of the shapes?

Solution

These shapes all show reflective symmetry, since one half of the object reflects the other half.

• ### Can you sort the objects into the type of symmetry shown?

Hints

Here is an example of rotational symmetry. Which two images above can be turned around a central point and still look the same?

Here is an example of reflective symmetry. Which two images above can have a line of symmetry drawn through the middle?

Solution

Reflective symmetry

• 1
• 4
Rotational symmetry
• 2
• 3

• ### Which symmetry does the picture show?

Hints

One half of the flower reflects the other half.

The dotted line on the flower is the line of symmetry.

Solution

The picture of the flower has reflective symmetry, since one half of the object reflects the other half. The dotted line is the line of symmetry.

• ### Match the picture to the type of symmetry it shows.

Hints

Reflective symmetry is where one half of the object reflects the other half.

Rotational symmetry is where an object can rotate in any direction and still have a central point of symmetry.

Solution

Since the picture of the butterfly shows one half of the object reflecting the other, this is an example of reflective symmetry.

Since the picture of the kite shows one half of the object reflecting the other, this is an example of reflective symmetry.

Since the hexagon can be rotated around the central point and not change, this is an example of rotational symmetry.
