Description: A polyhedron is a three-dimensional figure with flat faces where each face of a polyhedron is a polygon. This video presents several examples of polyhedrons.

Because we exist in three dimensions, humans can’t directly experience four-dimensional shapes. Still scientists have developed theory around them. One example is the 

, which is a 4D version of the cube, in a similar manner to how the cube is the 3D version of a square.

A three-dimensional figure with flat faces, where each face is a polygon

A smooth-flowing line, which bounds a surface

Polyhedron where three or more triangle-shaped faces meet at a top point above the base

A two-dimensional shape which is bounded by vertices and straight line segments

A three-dimensional figure with two identical circular faces at the top and bottom, often called the bases. The bases are connected by a curved surface.

A two-dimensional surface/side in a solid figure which is curved

A prism is a solid figure with flat faces. The top and bottom surfaces are identical polygons and the side faces are parallelograms.

A regular polygon with 5 edges and 5 vertices
