Solid shapes
Distinguish solids by faces, edges, vertices, and curved surfaces.
Meaning
Solid shapes occupy volume in space. Prisms and pyramids are distinguished by polygonal faces, while cylinders, cones, and spheres use circular or curved-surface properties.
Example
A triangular prism has two parallel congruent triangular bases and three lateral faces, giving five faces altogether. Do not distinguish prisms from pyramids by base shape alone. A prism has two corresponding bases; a pyramid's lateral faces meet at one vertex.
