3. ### Slide 3 - What Is Symmetry?

• Symmetry is when an image can be folded along a line into two matching halves.
• An object or image is considered symmetrical when it can be folded into two matching halves such as the heart below.
4. ### Slide 4 - Line of Symmetry

• The line that cuts an image exactly in half.
• horizontal, vertical, diagonal
5. ### Slide 5 - For Example:

• A butterfly has symmetry.
• If you draw a line down the center of a butterfly, both sides are the same!
6. ### Slide 6 - More Examples:

• Many kinds of food have symmetry!
• Many living things have symmetry!
• Even people have symmetry – most of the time!

8. ### Slide 8 - the same!

• The 2 sides are
• The 2 sides are
• symmetrical!

10. ### Slide 10 - VERTICAL

• up and down
11. ### Slide 11 - Another kind of symmetry is HORIZONTAL symmetry.

• Horizontal means across or side to side.
12. ### Slide 12

• For Example:
• Many common objects have horizontal symmetry!
• This bow and arrow has horizontal symmetry.!
• This ladybug has horizontal symmetry
13. ### Slide 13

• HORIZONTAL
• side to side
14. ### Slide 14 - Sometimes, objects have both vertical and horizontal symmetry:

• vertical
• AND horizontal
15. ### Slide 15

• Can you see the symmetry in this pattern?

16. ### Slide 16

• Which of these patterns is symmetrical?
• Nope!
• Nope!
• Yes!(one line of symmetry)
17. ### Slide 17

• This pattern is not symmetrical!
• Which of these patterns is NOT symmetrical?
18. ### Slide 18
