The shape that has 8 triangular faces and 12 edges is known as a triangular prism. In a triangular prism, two triangular faces are connected by three rectangular faces, but when considering only the triangular faces, it can also refer to a more complex polyhedron, specifically a truncated tetrahedron, which has 4 triangular faces and 4 hexagonal faces. However, if strictly adhering to the triangular face count, the triangular prism fits the description as it has triangular faces as part of its structure.
The shape with all triangular faces is called a tetrahedron. A tetrahedron has four triangular faces, six edges, and four vertices. It is the simplest three-dimensional shape in geometry and is a type of polyhedron. If you're looking for a shape with eight triangular faces, that would be a triangular bipyramid.
A shape that has 8 triangular faces is a octahedron.If you want to see a picture of a octrahedron here is a website.http://en.wikipedia.org/wiki/File:Octahedron.svgI had this as a maths question it was hard.
A shape that has some triangular faces is a pyramid.
It is an octahedron which is one of the Platonic Solids having 8 equilateral triangular faces and 12 edges.

A triangular based pyramid
A shape that has fewer than 8 faces and fewer than 10 edges is a triangular prism. A triangular prism has 5 faces (2 triangular faces and 3 rectangular faces) and 9 edges. It meets the criteria of having fewer than 8 faces and fewer than 10 edges.
