Three-Dimensional Figures

Parts of 3-D figures

• Face: A flat surface or side of a figure.

• Edge: The line segment which connects the faces.

• Vertex: Where edges connect (corners).

• Apex: The tallest point of a pyramid or cone.

• Base: A face(s) that is perpendicular to the height of the figure. Bases are connected by rectangles!

How do we name figures?

• Figures are named by their base shape and how many bases they have!

• If a figure has...

• 2 bases, it is a prism or cylinder

• 1 base, it is a pyramid or cone

How many faces, edges, vertices, and bases does this figure have?

What is the name of this figure?

We can also name shapes by using their net!

What is the definition of a net in math?
