2. Objectives:
 Define three-dimensional figures
 Identify the parts of a 3D figure
 Identify and describe attributes of three-dimensional
shapes including prisms, pyramids,
spheres, cones, and cylinders using appropriate
vocabulary.

3. What are three-dimensional figures?
 These figures are solid or hollow, you
could hold them in your hand.
 They have length, width,
and height.
 They are also called
solid geometric figures.

4. Solid Figures can have:
Surface
Face
Base
Edge
Corner
Edge

5. Surface
• The curved part of
a 3D shape.
• Cylinders and cones
have surfaces.

6. Face
• Part of a 3D
figure that is flat.
• The side of a 3D
figure.

7. Base
• The bottom
face of a
3D object.
Base

8. Edge
• The line where
two faces meet
on a 3D object.

9. Corner
• The point where
three or more
edges touch.

10. Vertex (Vertices)
• The point where
three or more
edges meet.
• This cube has 12
vertices all
together.

11. TYPES OF THREE-DIMENSIONAL
FIGURES
(SOLID FIGURES)

12. Cube
• A three-dimensional shape which
has:
– 6 square faces with the same sizes
– 12 edges
– 8 vertices
– 8 corners

13. Cube
• Some faces are parallel.
• Some edges are parallel.
• Some faces are
perpendicular.
• Some edges are
perpendicular.

14. Cube
• Cubes in daily life:
– A box
– Blocks
– Dice

15. Sphere
• A perfectly round three-dimensional
shape, like a ball.
• It has only one curved
surface.
• A sphere has no
face,edge,vertex and corner.

16. Sphere
• Spheres in daily life:
– A Ball
– A Globe
– A Marble

17. Cone
• A three-dimensional shape
made up of:
– a circular base
– a curved surface that comes to a
point at the top (vertex).
• A Cone has no edge and corner.

18. Cone
• Cones in daily
life:
– Ice Cream Cone
– A Party Hat

19. Cylinder
• A three-dimensional shape
with one curved surface and
2 equal circles as its base.
• A Cylinder has 2 faces, 1
surface, no edges and
no corners.

20. Cylinder
• Cylinders in daily
life:
– A Soup Can
– A Roll of Toilet
Paper

21. Pyramid
• A three-dimensional
shape which has a
polygon for its base
and triangular faces
which meet at one
point (vertex).

22. Rectangular Prism
• A 3D shape that has:
– 6 rectangular faces
• 2 of those faces
are equal
– 12 edges
– 8 vertices

23. Rectangular Prism
• Some faces are parallel
• Some edges are parallel
• Some faces are
perpendicular
• Some edges are
perpendicular

24. Rectangular Prism
• Rectangular prism in
daily life:
– A Kleenex Box
– A Refrigerator
– A Cereal Box
