A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
octahedron
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.
Only if it is a regular tetrahedron, regular octahedron, or regular icosahedron. All other geodesics have isosceles triangle faces, not equilateral triangles.
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).

Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.

A regular octahedron.
A regular octahedron has 8 faces, 12 edges, and 6 vertices. Each face is an equilateral triangle, and the octahedron can be thought of as two pyramids with a square base joined at their bases. This structure contributes to its symmetrical properties and distinct geometric characteristics.
