What has 8 congruent equilateral triangles as faces and 6 vertices?
A solid with 8 faces is an octahedron.As all faces are the same it is a regular octahedron.As such it is one of the five platonic solids - the only five 3D objects that can be regular: the tetrahedron (4 equilateral triangles for the faces), the hexahedron (usually called a cube with 6 square faces), the octahedron (as asked, 8 equilateral triangles for the faces), dodecahedron (12 regular pentagons as faces), icosahedron (20 equilateral triangles as faces).

What is a Polyhedron with eight sides that are triangles?
Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.
How many congruent faces are on a triangular prism?
