WebIn geometry, a polyhedron is a three-dimensional object with flat polygonal faces, sharp corners and straight edges. Each side is a flat surface and is without any curved surfaces. The word comes from the Greek 'poly' (stem of many) + 'hedron' (face). So, a polyhedron basically means 'many faced geometric shape.'. WebThe properties of platonic solids are: Platonic solids have polygonal faces that are similar in form, height, angles, and edges. All the faces are regular and congruent. Platonic shapes are convex polyhedrons. The same number of faces meet at each vertex. Platonic solids are three-dimensional, convex, and regular solids shapes.
