Is a decahedral a regular polygon?
No it isn't a regular polyhedron
Is decahedral a regular polyhedron?
no because they don't have the same sides or vertices as the regular ones which are tetrahedral, octahedral, dodecahedral, icosahedral, they are all regular polydrons but not decahedral
Is a Decahedral die an irregular polygon?
It is not a polygon at all, it is a polyhedron. It is irregular.
Is a decahedral die a regular polyhedral?
NO
Is a octahedral die a regular polyhedron?
Yes, it is.
Is a dodecahedral die a regular polyhedron?
It can be, but need not be.
Why decahedron is not a regular polyhedron?
It is not a regular polyhedron because it has unequal sides
Is a truncated isocahedron a regular polyhedron?
No. It is a semi-regular polyhedron. Explanation. The truncated icosahedron is a polyhedron that can be constructed from an icosahedron with the 12 vertices truncated (cut off) such that one third of each edge is cut off at each of both ends. This creates 12 new pentagon faces, and leaves the original 20 triangle faces as regular hexagons A regular polyhedron is a polyhedron whose faces are congruent regular polygons. The truncated icosahedron is NOT a regular polyhedron, it is a semiregular polyhedron. It is a uniform polyhedron.
Is a sphere a polyhedron?
No, a sphere is not a polyhedron.A polyhedron is a three-dimensional geometric figure whose sides are polygons.A regular polyhedron is a polyhedron whose faces are all congruent regular polygons.
Why is a rectangle polyhedron not regular polyhedron?
The sides of a rectangle are not all equal so a rectangle is not a regular polygon. And, as a consequence, any 3-dimensional shape made from rectangles cannot be a regular polyhedron.
Is a cylinder a regular polyhedron?
No, it is not.
Is a decahedron a regular polyhedron?
No.
