Identify the figure. Then name the bases, faces, edges, and vertices. Identify Solids Identify the figure. Then name the bases, faces, edges, and vertices. Answer: The figure has two parallel congruent bases that are octagons, so it is an octagonal prism. bases: ABCDEFGH, IJKLMNOP faces: ABCDEFGH, IJKLMNOP, ABKJ, BKLC,CLMD, DMNE, ENOF, FGPO, GHIP, HAJI Example 1

Identify the figure. Then name the bases, faces, edges, and vertices. Identify Solids Identify the figure. Then name the bases, faces, edges, and vertices. Answer: edges: vertices: A, B, C, D, E, F, G, H, I, J, K, L, M, N, O, P Example 1
