You have already modeled three-dimensional
figures. (Lesson 12–1a)
• Identify three-dimensional figures.
• Describe and draw vertical, horizontal, and
angled cross sections of three-dimensional
figures.
Prism vs. Pyramid
Identify Solids
Identify the figure. Name the bases,
faces, edges, and vertices.
Answer: This figure has two
parallel congruent bases
that are rectangles, so it
is a rectangular prism.
bases: GHJK and LMNP,
edge
base
face
vertex
faces: GHJK, LMNP, GHML, HJNM, JKPN, GKPL
edges:
vertices: G, H, J, K, L, M, N, P
Identify the figure. Name the
bases, faces, edges, and
vertices. Which listing is
not accurate?
A. rectangular pyramid with base: BCDE
B. faces: ABC, ACD, ADE, AEB, BCDE
C.
D. vertices: B, C, D, E
