A polyhedron with equilateral triangular faces is called a deltahedron. There are infinitely many of them but only 8 convex ones. The following three are regular:
tetrahedron, octahedron and icosahedron.
There are 5 more convex polyhedra which are convex but not regular (because they have differing number of faces meeting at their vertices) These are Johnson deltahedra (see link).
What else can I help you with?
What is a polyhedron that has eight faces and has all faces that are equilateral triangles?
octahedron
What is a polyhedron with all faces the same all faces are equilateral triangles and has eight faces?
tetrahedron
You are a polyhedron all faces are the same all faces are equilateral triangles i have 8 faces?
Octohedron, or rhomboid.
I am a polyhedron. All my faces are the same. All my faces are equilateral triangles. I have 8 sides?
A regular octahedron.
Is the tetrahedron a regular polyhedron?
Not necessarily. If all faces are equilateral triangles (all edges are equal length) then it is a regular polyhedron.
