Symmetry Presentation By Sharanya

  1. 1. Symmetry Line symmetry & Rotational symmetry
  2. 2. What is Symmetry? Symmetry is when an object has two or more equal sides when split in half or in smaller pieces. The tiger has 1 line of symmetry .
  3. 3. What is line Symmetry ? A shape has line symmetry when one half of it is the mirror image of the other half.
  4. 4. This butterfly has 1line of symmetry This image has 2 lines of symmetry
  5. 5. Symmetry with alphabets
  6. 6. Circle has infinite lines of symmetry Square has 4 lines of symmetry Rectangle has 2 lines of Symmetry
  7. 7. This smiley face has 1 line of symmetry
  8. 8. This symbol has 3 lines of symmetry This flag has 4 lines of symmetry
  9. 9. What is Rotational symmetry ? An image has Rotational Symmetry if there is a centre point around which the object is turned a certain number of degrees and the object still looks the same, ie it matches itself a number of times while it is being rotated Since this triangle will match itself 3 times as it is rotated it is said to have rotational symmetry of Order 3.
  10. 10. Since all the toppings are  placed so evenly, this pizza has rotational symmetry of Order 6. This flower has rotational symmetry of Order 5 since it matches itself 5 times..
  11. 11. This Swastika has rotational symmetry of order 4
  12. 12. Some examples of rotational symmetry Rotational order 5 Rotational order 2 Rotational order 4
