1. Geometric Solids

2. What is a geometric solid?

3. What is a geometric solid?
A closed three dimensional object made up of flat surfaces which are geometric shapes.

4. How do we classify solids?
We classify solids based on their faces, edges and vertices.

5. The flat surface on a solid figure
What IS a face?
The flat surface on a solid figure

6. The line where two faces meet.
What is an edge?
The line where two faces meet.

7. The corner where edges and faces meet.
What is a vertex?
The corner where edges and faces meet.

8. 1.) Explain how faces, edges, and vertices are different.
SUMMARY
1.) Explain how faces, edges, and vertices are different.

9. What do these all have in common?
Prisms
What do these all have in common?
They all have at least one set of parallel faces.
A prism is a solid with parallelograms for sides and a set of parallel, congruent bases.

10. Parallel faces are Triangles
Triangular Prisms
Parallel faces are Triangles

11. Parallel faces are Rectangles
Rectangular Prisms
Parallel faces are Rectangles

12. Cubes
All faces are squares

13. What are these Prisms? Octagonal Prism Hexagonal Prism
Pentagonal Prism

14. SUMMARY
1.) What is a prism?

15. What do these all have in common? They all come to a point at the top.
Pyramids
What do these all have in common?
They all come to a point at the top.
A pyramid is a solid with triangular sides and only one base.

16. Rectangular Pyramids
The base is a rectangle

17. Triangular Pyramids
The base is a triangle

18. Which are pyramids?

22. What do these all have in common?
Cylinders
What do these all have in common?
They all have a set of parallel circular bases.
A cylinder is a solid with a set of parallel, congruent, circular bases.

23. The parallel bases are circles
Cylinders

25. What do these all have in common?
Cones
What do these all have in common?
They all have a circle at the bottom and a point at the top.
A cone is a solid with one circular base and a point at the top.

26. Cones
