1. Three –Dimensional Figures
-What is the difference between prisms and pyramids?

2. What are three-dimensional figures?
A three-dimensional figure encloses a part of space.
In other words it can hold something (water, air, etc.)
It has Volume.

3. Features of a 3-D figure Face- the flat surface of a figure
Vertex
Edge
Edge- formed by two faces of a 3-D figure sharing a side
Faces
Vertex (plural:vertices)- the point at which three or more edges meet

4. Identify the number of faces, edges, and vertices on each three-dimensional figure.

5. Identify the number of faces, edges, and vertices on each three-dimensional figure.

6. Two main types of 3-D Figures
Prism:
Has at least three faces that are rectangles
Has two congruent faces on the top and bottom called bases
The shape of the base tells what type of prism the figure is
Pyramid:
Has at least three faces that are triangles
Has only one base
The shape of the base tells what type of pyramid the figure is

7. Prisms
Rectangular Prism
Triangular Prism

8. Pyramids
Square Pyramid
Triangular Pyramid

15. Polyhedron A 3-dimensional figure that has polygons as faces
Polygons must have straight lines!
