Advertisement Properties of Dodecahedrons Sides – A dodecahedron has 12 pentagonal sides. Edges – A dodecahedron has 30 edges. Vertices – It has 20 Vertices (corner points), and at each vertex 3 edges meet 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 faces does a dodecahedron have? The dodecahedron has 30 edges, 20 vertices and 12 faces This article was adapted from an original article by BSE-3 (originator), which appeared in Encyclopedia of Mathematics - ISBN See original article How many sides does a dodecahedron have? See answers Advertisement Advertisement sss sss From left to right the solids are tetrahedron (four sides), cube (six sides), octahedron (eight faces), dodecahedron (twelve faces), and icosahedron (twenty faces). Advertisement Advertisement Definition: What does Dodecahedron mean? A dodecahedron is a three-dimensional shape that is made up of twelve flat faces. Each face is a regular pentagon, which means all sides and angles are equal. The dodecahedron is one of the five Platonic solids, which are convex polyhedra with faces composed of congruent regular polygons
Dodecagon - Wikipedia
A dodecahedron with sidelength a a has 60 60 surface diagonals and space diagonals, 10 10 being long, 30 30 being medium, and 60 60 being short. I have figured out length of long diagonal is a 1 +ϕ4− −−−−√ a 1 + ϕ 4 and medium diagonal is aϕ2 a ϕ 2 but I couldn't find the short diagonal. geometry. solid-geometry It has 20 faces. The number of edges will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with gons as bases, will have 54 edges. On the other hand a pyramid with a gon base will have 38 edges. A bipyramid with a decagon base will have 30 edges.

See answer Advertisement Advertisement aryansreepuram aryansreepuram Answer: A dodecahedron has 12 sides. It is one of the five regular polyhedra, known as the Platonic solids, and each of its 12 faces is a regular pentagon, meaning it has five sides of equal length and five angles of equal measure 12 pentagonal faces. 20 vertices. 30 edges.

A Missing: angel The dodecahedron is a Platonic solid, which has all its faces with a pentagonal shape. A dodecahedron consists of 12 faces, 30 edges, and 20 vertices. Three pentagonal faces meet at each vertex. An interesting property of dodecahedrons is that they have diagonals. In addition, these figures can be seen commonly in real life, especially in
How many sides are in a dodecahedron? - CK-12 Foundation
Answer: the correct answer is 12 sides (: Explanation: How many sides does a dodecahedron have? - [HOST] See what teachers have to say about Brainly's new learning tools! How many sides would a regular polygon have if one of its exterior angles measures 30 degrees? If one of its exterior angles is 30 degrees, then it is a star with 6 points and 12 sides. degrees / 30 degrees = 12 angles It is a regular dodecahedron. 10 sides and 10 angles Two types of star pentagons {5/2} |5/2| A regular star pentagon, {5/2}, has five corner vertices and intersecting edges, while a concave decagon, |5/2|, has ten edges and two sets of five [HOST] first are used in definitions of star polyhedra and star uniform tilings, while the second are sometimes used in planar tilings.: Small stellated dodecahedron
