pyramid
it is a term for a face , its different for all, if the polyhedron is based off a 2d polygon, it is the side with that shape(usualy)(their may be more than one)
A polyhedron is a closed figure with several (planar) sides, and all its sides are planar. A non polyhedron does not have these properties, maybe it is not closed, maybe one or more of the sides is a curved surface. In some branches of topology the sides of a polyhedron cannot intersect each other.
All of them. If its truly intersecting lines, they have to form right angles. All of them. If its truly intersecting lines, they have to form right angles.
must all edges of semiregular polyhedron be the same length
What polyhedron has eight sides and all of the are equilateral triangle?
It is a definitional requirement. If any face is not flat, then it is not a polyhedron.
No, a polyhedron is a three-dimensional solid bounded by polygonal faces. Each face is a flat polygon, and the edges of these polygons meet at vertices. The term "two-dimensional solid" is a mischaracterization, as polyhedra occupy three-dimensional space.
An eight-face polyhedron is called an octahedron.

An apex is the point at the top of a polyhedron where all the sides meet. example: the top of a pyramid.
A solid that has faces that are the same size and shape is called a regular polyhedron. The faces of a regular polyhedron are all congruent, meaning they are identical in shape and size. For example, a cube has six square faces, all of which are the same size and shape. The term for each individual face is simply referred to as a "face."
A polyhedron is a simply connected 3-dimensional shape whose faces are all regular polygons. A hexagonal pyramid is a special case in which one face is a hexagon and six faces are triangles.

You are a regular octahedron. An octahedron is a type of polyhedron that has eight faces, all of which are equilateral triangles. It is one of the five Platonic solids and has twelve edges and six vertices.
I believe that the only polyhedron or polygon that own all of these features to be a sphere
A tetrahedron (triangular pyramid).
A polyhedron is a plane shape, enclosing a single space, which is bounded by straight lines.If ALL angles and ALL sides are equal, then it is a regular polyhedron. All other polyhedra are irregular.Note that if any of the sides is not straight then the shape is not a polyhedron at all, and so cannot be an irregular polyhedron.A polyhedron is a plane shape, enclosing a single space, which is bounded by straight lines.If ALL angles and ALL sides are equal, then it is a regular polyhedron.
