3-D Shapes

An Introduction to Surface Area. (A copy of this document is available for you in the HUB)

Parts of a 3D figure

• Faces: flat sides

• Edges: lines in between 2 faces

• Vertices: corners or points where edges connect

Prisms:

• TWO parallel bases

• Rectangular faces

• Names come from the bases

• Example: The triangular prism has two triangle bases
