1. 1. SymmetryLine symmetry & Rotational symmetry
2. 2. What is Symmetry?Symmetry iswhen an objecthas two or moreequal sideswhen split inhalf or in smaller The tiger has 1pieces. 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 image has 2 lines of symmetryThisbutterflyhas 1line ofsymmetry
5. 5. Symmetry with alphabets
6. 6. Square has 4lines ofsymmetry Circle has infinite lines of symmetry Rectangle has 2 lines of Symmetry
7. 7. This smiley facehas 1 line ofsymmetry
8. 8. This symbol has 3 lines of symmetryThis flag has 4 linesof symmetry
9. 9. What is Rotational symmetry ?An image has Rotational Symmetry if there is acentre point aroundwhich the object is turned a certain number ofdegrees and the objectstill looks the same, ie it matches itself a number oftimes 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 flowerhas rotationalsymmetry ofOrder 5 sinceit matchesitself 5 times..
