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 diagonals,60 face diagonals, space diagonals Dodecahedron. A dodecahedron is a polyhedron with 12 faces. In the figure below are 2 different types of dodecahedrons. The prefix "dodeca" means twelve. Because of their Missing: angel A polygon has 20 diagonals how many sides does it have? It is an octagon with 8 sides. Let n be the number of sides = number of vertices. Then each vertex can be connected to n-3 other vertices, giving n(n -3) connections. However, this counts each vertex pair connection twice, so there are: n(n - 3) / 2 diagonals 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 A dodecahedron has: 12 faces (each face is a regular pentagon with 5 sides) 30 edges; 20 vertices; Angles. The angle between 2 sides of a pentagonal face Missing: angel

How many faces does a truncated dodecahedron have? The Truncated Dodecahedron has 20 equilateral triangular faces, and 12 regular decagonal faces. The 20 triangles come from the 20 cuts that were made at each vertex and are added to the 12 original dodecahedral faces to make 32 total faces. There are 60 Vertices and 90 Edges 'dodeca' should be about ''Hedron'' - I cheated and looked it up. My answer for now: too many sides to count unless one day it may be - Other Question How many sides does a Rhombic dodecahedron have? A rhombic dodecahedron is a 3-D shape (polyhedron) that has 12 rhombic faces, 24 edges (sides), and 14 vertices (points). Its dual is a cuboctahedron Dodecahedron. Properties of the dodecahedron: Number of faces, edges and dihedral angle measure. The dodecahedron is one of the five Platonic solids. 12 faces: regular pentagons. 20 vertices. 30 edges. Dihedral angles: degrees, 34 minutes. What's a Prime Number? Converting Fractions to Decimals 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 Missing: angel
How many angles does a dodecahedron have? - Answers
Since all 12 pentagonal faces of the dodecahedron have the same dimensions, we just have to find the area of one of the faces and multiply the result by 12 to get the surface Missing: angel Note that each of the sides is a regular polygon, and if you rotate any Platonic solid by an edge you have two-fold [HOST] you rotate it around opposite vertices or the centers of opposite faces, you have symmetry of order 3, 4 or Another symmetry of the Platonic solids is that they are duals of each other. That is, if you take the centers of all How many sides does each face of a dodecahedron have? 12 sides Dodecahedron is derived from the Greek word “dōdeka” means “12” and “hédra” means “face or seat” that shows that it is a polyhedron with 12 sides or 12 faces. Hence, any polyhedra with 12 sides can be called a dodecahedron. It is made up of 12 pentagonal faces How many sides are in a dodecahedron? Q: How many sides are in a dodecahedron? How many sides are in a dodecahedron? Flexi Says: A dodecahedron is formed by Missing: angel 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 How many sides does a dodecahedron have? Get the answers you need, now! sanjanareddythooti sanjanareddythooti Step-by-step explanation: 12 Sides. Advertisement Advertisement evab evab Answer: 12 sides. I hope this is the right. Advertisement Advertisement New questions in Math. Euclid's fifth postulate 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. There are very many more possible
