What is dodecahedron made up of?
What is dodecahedron made up of?
12 congruent pentagons
A dodecahedron is made up of 12 congruent pentagons with 3 pentagonal faces meeting at each of its 20 vertices. There are two types of dodecahedrons – regular and irregular dodecahedrons.
How many faces are there on a dodecahedron?
12Dodecahedron / Number of faces
How many nets does a dodecahedron have?
43380 distinct
There are 43380 distinct nets for the regular dodecahedron, the same number as for the icosahedron (Bouzette and Vandamme, Hippenmeyer 1979, Buekenhout and Parker 1998).
How many edges does a regular dodecahedron have?
30 edges
A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular, which is composed of 12 regular pentagonal faces, three meeting at each vertex. It is one of the five Platonic solids. It has 12 faces, 20 vertices, 30 edges, and 160 diagonals (60 face diagonals, 100 space diagonals).
How many sides are in a dodecahedron?
twelve
In geometry, a dodecahedron (Greek δωδεκάεδρον, from δώδεκα dōdeka “twelve” + ἕδρα hédra “base”, “seat” or “face”) or duodecahedron is any polyhedron with twelve flat faces. The most familiar dodecahedron is the regular dodecahedron with regular pentagons as faces, which is a Platonic solid.
Which is a regular polyhedron?
A regular polygon is a (convex) planar figure with all edges equal and all corners equal. A regular polyhedron is a solid (convex) figure with all faces being congruent regular polygons, the same number arranged all alike around each vertex.
What is a regular polyhedron Class 8?
A polyhedron is a regular polyhedron if its faces are formed by the regular polygons and the same number of meet at each vertex.
How many sides does a Dodecagon have?
12-sided
A dodecagon is a 12-sided polygon. Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon.
How many vertices are on a dodecahedron?
20Dodecahedron / Number of vertices
How many sides are in a dodecagon?
12Dodecagon / Number of edges
