This document defines and describes various three-dimensional figures. It begins by defining 3D figures as solid objects that have length, width, and height. The parts of 3D figures are then identified as surfaces, faces, bases, edges, corners, and vertices. Examples are provided of common 3D shapes like cubes, spheres, cones, cylinders, pyramids, and rectangular prisms along with their characteristics and real-world examples. The document aims to build understanding of 3D geometry terms and the attributes of different three-dimensional shapes.

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
