It is a face of the polyhedron
Yes, a trapezoidal prism is a polyhedron. A polyhedron is a solid three dimensional object with flat face, straight edges and sharp corners.
Octogon
Yes it is a tetrahedron
A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
It is a face of the polyhedron
Each surface of a polyhedron is called a face.
Yes. A base on a polyhedron is a face and a base on a polygon is a side.
The face of a polyhedron is any of its flat surfaces
It is called a face of the polyhedron.
Any polygon can be a face of a polyhedron.
For every polyhedron, there is a dual which is a polyhedron that has:a face where the first had a vertex,a vertex where the first had a face,the same number of edges.A self-dual polyhedron is a polyhedron whose dual is the same shape.All pyramids, for example, are self-dual.
4The minimum number of face a polyhedron can have is four.
No. A polyhedron has plane faces; a cylinder has one curved face.
square and hexagon
It is a definitional requirement. If any face is not flat, then it is not a polyhedron.
