Abstract
Apolyhedron is a 3D shape whose boundaries or faces
are planar polygons. Two faces meet along an edge
while three or more faces meet at a vertex. Among
polyhedra we have the five Platonic solids. All the faces of a
Platonic solid are congruent regular polygons. These five were
identified by ancient Greek geometers who also proved that no
other polyhedron has this property (i.e., of having faces that
are regular polygons of the same size and the same number
of sides). One example of a Platonic solid is the icosahedron,
which has 20 faces that are congruent equilateral triangles. It
has 30 edges and 12 vertices.
