    Slide 1 - Symmetry

  2. I can:Recognize a line of symmetry.Draw a line of symmetry.Identify lines of symmetry in two dimensional figures.Draw figures that have lines of symmetry.

    Slide 2 - I can:Recognize a line of symmetry.Draw a line of symmetry.Identify lines of symmetry in two dimensional figures.Draw figures that have lines of symmetry.

  3. What Is Symmetry?

    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. Line of Symmetry

    Slide 4 - Line of Symmetry

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

    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. More Examples:

    Slide 6 - More Examples:

    • Many kinds of food have symmetry!
    • Many living things have symmetry!
    • Even people have symmetry – most of the time!
  7. Sometimes, even very complicated things have symmetry:

    Slide 7 - Sometimes, even very complicated things have symmetry:

  8. the same!

    Slide 8 - the same!

    • The 2 sides are
    • The 2 sides are
    • symmetrical!
  9. When the line of symmetry goes up and down,It is called VERTICAL symmetry

    Slide 9 - When the line of symmetry goes up and down,It is called VERTICAL symmetry

  10. VERTICAL

    Slide 10 - VERTICAL

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

    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. Sometimes, objects have both vertical and horizontal symmetry:

    Slide 14 - Sometimes, objects have both vertical and horizontal symmetry:

    • vertical
    • AND horizontal
  15. Slide 15

    • Can you see the symmetry in this pattern?
    • This object has two lines of symmetry
  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

    • Does this object have vertical symmetry or horizontal symmetry?
    • Both!
    • In fact, you could argue that this object has 4 lines of symmetry! (although not exactly)
