1. 2-Dimensional Shapes (2D Shapes) 2 D shapes only have two dimensions, such as width and length Some are: Polygons and Some are: Not Polygons

2. Polygons • Polygons are flat and contain straight sides that are connected.

3. Examples of Polygons • Include……..

4. Triangles • Have 3 sides

5. Quadrilaterals Diamonds also known as a rhombus • Have 4 sides squares rectangles

6. Pentagons • Have 5 sides

7. Hexagons • Have 6 sides

8. Heptagons • Have 7 sides

9. Octagons • Have 8 sides STOP

10. Nonagons • Have 9 sides

11. Decagons Have 10 sides

12. Undecagons Have 11 sides

13. Not Polygons Hearts Ovals Circles Non closed shapes

14. What is a 2D shape that has straight sides that are connected? polygon

15. What is a quadrilateral? • A 4-sided polygon. • Examples include: squares, rectangles, diamonds, etc.

16. What is a 3 sided polygon? • A triangle

17. What is a 5 sides polygon? • A pentagon

18. What is a 6 sided polygon? • A hexagon

19. What is an 8 sided polygon? • An octagon

20. Now you should know a little more about 2 D shapes!
