In geometry, an icosahedron (/ˌaɪkɒsəˈhiːdrən, -kə-, -koʊ-/ or /aɪˌkɒsəˈhiːdrən/) is a polyhedron with 20 faces. The best known is the (convex, non-stellated) regular icosahedron—one of the Platonic solids—whose faces are 20 equilateral triangles.
What is a 20 sided shape called?
icosagon
In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon’s interior angles is 3240 degrees.
What 3d shape has the most faces?
- In geometry, the rhombicosidodecahedron, is an Archimedean solid, one of thirteen convex isogonal nonprismatic solids constructed of two or more types of regular polygon faces.
- It has 20 regular triangular faces, 30 square faces, 12 regular pentagonal faces, 60 vertices, and 120 edges.
What is a 3d shape with 100 faces called?
If a 3d shape with 100 faces is called hecatohedron. In case of two dimensional shapes, a shape with 100 sides is called Hectogon. The relationship between the number of faces, edges and vertices of a 3d shape is given by: F + V = E + 2.
What type of shape is a dodecahedron?

What are the faces vertices and edges of a 3D shape?
This video and images below explain the faces, vertices and edges of common three-dimensional shapes. A face is a 2D shape that makes up one surface of a 3D shape, an edge is where two faces meet and a vertex is the point or corner of a geometric shape.
What is a 3D shape?
A 3D shape is described by its edges, faces, and vertices (vertex is the singular form of vertices).
What is the area of a face of a 3D shape?
A face is a 2D shape that makes up one surface of a 3D shape, an edge is where two faces meet and a vertex is the point or corner of a geometric shape. To work out the area of a face of a 3D shape, you use square units such as cm 2 as the face of a 3D shape is a 2D shape in its own right (a pyramid’s face will form a triangle,…
What are the three parts of a three dimensional shape?
Three dimensional shapes can be picked up and held because they have length, width and depth. Faces are the surfaces on the outside of a shape. Edges are the lines where two faces meet. Vertices (or corners) are where two or more edges meet.
