Polygon vs. Polyhedron POLYGON: A plane shape (two-dimensional) with straight sides. POLYHEDRON: A solid with flat faces (from Greek poly- meaning "many" and -edron meaning "face"). Example: pyramids and prisms
Box 1 Solid Shapes Box 2 Box 3 Box 4 Box 5
Box 1: 3 -Dimensional figures are not flat figures. They have length, width, and height.
Box 2:
Box 5: Face: Face is the flat surface Edge: Edge is a line that connects faces together. Vertices: Vertex is a point where edges and or multiple faces meet.

Rectangular prism face edge base vertex A rectangular prism has 6 faces, 8 vertices, 12 edges, and 2 bases.
Cube face vertex edge A cube, just like a rectangular prism, has 6 faces (all squares), 8 vertices, 12 edges, and 2 bases.
Rectangular Pyramid A rectangular pyramid has 5 faces. Its ONE base is a rectangle and the other 4 faces are triangles. It has 8 edges and 5 vertices.
Triangular pyramid vertex face base A triangular pyramid has four faces. All faces, including its ONE base, are triangles. It has six ed and four vertices.
Triangular prism base face vertex A triangular prism has five faces. Its base is a triangle. (Notice that even when the triangular prism sits on a rectangle, the base is still a triangle. ) Two of its faces and the TWO bases are triangles; three of its faces are rectangles. It has six vertices and nine edges.
Square pyramid face vertex base A square pyramid has 5 faces. Its base is a square and the other 4 faces are triangles. It has 8 edges and 5 vertices.
