The figure described is a polyhedron. It is a tetrahedron known as a triangular pyramid.
The answer is a polyhedron
A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
Yes. A tetrahedron is a closed 3-d shape with 4 triangular faces. In a regular polygon, each of these is an equilateral triangle.
Regular Tetrahedron
There is no such thing as a 3d triangle. A 3d shape which has only equilateral triangular faces can be a tetrahedron which has 4 faces or an icosahedron which has 20.

An icosahedron is a regular polyhedron with 20 equilateral triangle faces.

The shape with four triangular faces that are all equilateral is a tetrahedron. A tetrahedron is a type of polyhedron that has four vertices, six edges, and four triangular faces. Each face is an equilateral triangle, making it one of the simplest three-dimensional shapes.

octahedron
Oh, dude, an equilateral triangle has 3 vertices, 3 faces (which are also the sides), and 3 edges. It's like the most balanced shape ever, so chill.
