1. Lesson 10.3 Three-Dimensional Figures
Essential Question: How do you classify solids?

2. Before we start… What is a polygon?
Name the polygons with the given number of sides: 4 5 6 8 10

3. What is a solid?
A three-dimensional figure that encloses a part of space

4. What is a polyhedron?
A solid that is enclosed by polygons; it has only flat surfaces.

5. What is a face?
The polygons that form a polyhedron
Face

6. How do you classify solids?
The base of the solid determines which one it is.

7. What is a prism? A polyhedron Two congruent bases in a parallel plane
Other faces are rectangles

8. What is a pyramid?
A polyhedron
One base
Other faces are triangles

9. What is a cylinder? A solid
Two congruent circular bases in parallel planes

10. What is a cone?
Solid
One circular base

11. What is a sphere?
Solid
All points in space are the same distance from a fixed point called the center

12. What a cube?
A polyhedron
A prism
Six square faces

13. Classify the solid. Is the solid a polyhedron?

14. Classify the solid. Is the solid a polyhedron?

15. What is an edge?
The segments where faces of a polyhedron meet
Edge

16. What is a vertex?
A point where three or more edges meet
Vertex

17. Classify the solid. Then count the number of faces, edges, and vertices.

18. Classify the solid. Then count the number of faces, edges, and vertices.

19. Classify the solid. Then count the number of faces, edges, and vertices.

20. Classify the solid. Then count the number of faces, edges, and vertices.

21. Sketch a triangular prism.

22. Sketch a cylinder.

23. Sketch a rectangular prism.

24. Sketch a hexagonal prism.
