tetrahedron
Octohedron, or rhomboid.
A regular octahedron.
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).
Equilateral triangles have three sides of the same length.
An octahedron.

its a dedrehedron * * * * * Sadly, a dedrehedron does not exist. Fotunately, though, a regular octahedron does and it meets the specifications in the question.
No, a scalene is a scalene and an equilateral is an equilateral. They are NOT the same.
