1. Quadrilaterals and Symmetry By Chloe Lam 4B ( 16 )

2. Opening ceremony Good morning/afternoon Mr. Chiu, this is a power point about shapes and symmetry, hope you’ll enjoy it.

3. Contents Quadrilaterals Symmetry

4. Quadrilaterals Quadrilaterals are four sided shapes. e.g. -S-Square -R-Rectangle -K-Kite -r-rhombus -p-parallelogram

5. Square Four right angles Two pairs of parallel opposite sides Four sides are equal in length

6. Opposite sides are equal in length Opposite sides are parallel 4 right angles

7. Rhombus 4 sides are equal in length Opposite sides are parallel rhombus pattern

8. Kite Adjacent sides are equal in length A kite-cut diamond

9. Parallelogram Opposite sides are equal in length Opposite sides are parallel

10. Trapezium Opposite sides are parallel

12. The opposite of symmetry is asymmetry. e.g. symmetry in religious symbols symmetry in music symmetry in architecture symmetry in social interaction symmetry in poetry symmetry in literature symmetry in logic symmetry in physic symmetry in science symmetry in mathematics

13. Symmetry concept of balance or like the mirror, a shape with two side equal. the two sides are equal, so it is symmetric shape

14. Pictures of symmetry
