4. Y >_< I Y 一,一一,一 I Quadrilateral Quadrilateral are four-sided shapes. E.g. Squares, Rectangle, Rhombus,…

5. Y >_< I Y 一,一一,一 I Squares Four sides equal in length. Four right angles. Two pairs of parallel lines.

6. Y >_< I Y 一,一一,一 I Rectangles Four right angles. 2 pairs of opposite sides are equal in length. There are two pairs of parallel opposite sides.

7. Y >_< I Y 一,一一,一 I Kite There are 2 pairs of adjacent sides equal in length. The opposite sides are not parallel. There is 1 pair of opposite angles at the same size.

8. Y >_< I Y 一,一一,一 I Parallelogram 2 pairs of opposite sides are equal in length. 2 pairs of parallel opposite sides. 2 pairs of opposite angles at the same size.

9. Y >_< I Y 一,一一,一 I Trapezium There is only one pair of parallel opposite sides. The parallel sides are not equal in length.

10. Y >_< I Y 一,一一,一 I Symmetry Symmetry is a picture that the half side is the same of the half side. Let’s see some examples!

11. Y >_< I Y 一,一一,一 I MTR This is a example of symmetrical shape.

12. Y >_< I Y 一,一一,一 I Heart Heart is a symmetrical shape too!

13. Y >_< I Y 一,一一,一 I Apple Apple is a symmetrical shape also!
