Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.
You're an octagon.
Their faces are equilateral triangles.

tetrahedron
Assuming that "equal ladder" is meant to be equilateral, the answer is a tetrahedron, one of the 5 Platonic solids.

An octahedron.
What polyhedron has eight sides and all of the are equilateral triangle?
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).
In geometry, an octahedron (plural: octahedra) is a polyhedron with eight faces. A regular octahedron is a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.It is a 3-dimensional cross polytope (shape).---Wikipedia
