While a triangular prism can have equilateral triangle faces, it has more faces that are quadrilateral (or rectangular).
A polyhedron with only equilateral triangular faces could be a tetrahedron, an octahedron in the form of a square based dipyramid, or an icosahedron.
The answer is a polyhedron
Tetrahedron
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
An icosahedron is a regular polyhedron with 20 equilateral triangle faces.
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.
The answer is a polyhedron
Tetrahedron
What polyhedron has eight sides and all of the are equilateral triangle?
It is a triangular based pyramid
A regular OCTAHEDRON.
Tetrahedron - a pyramid with a triangular base.
A regular polyhedron has equal size faces as in the case of a tetrahedron which is a triangular base pyramid that has 4 equilateral triangle faces.
An icosahedron is a regular polyhedron with 20 equilateral triangle faces.
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.
that's easy its a triangle * * * * * That is such a nonsensical answer! A triangle is not even a polyhedron. The correct answer is an octahedron - two square based pyramids stuck together along their bases.
A 20-sided polyhedron is called an icosahedron. It has 20 equilateral triangle faces, 30 edges, and 12 vertices. It is a regular convex polyhedron with rotational symmetry.
