A regular octahedron is a Platonic solid with equilateral triangles for each of the faces.
A heptagonal pyramid is an octahedron with one heptagon (a seven sided figure) as its base and 7 triangles, one attached to each side, meeting at the either vertex.
A regular OCTAHEDRON.
how about 2 hexagons connected with 6 rectangles
8
octahedron
This object is called an octahedron
What polyhedron has eight sides and all of the are equilateral triangle?
yes
A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
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.
Not necessarily. A heptagon-based pyramid is an octahedron and it has no parallel faces.
A shape with 8 faces is called an octahedron. An octahedron is a polyhedron with eight faces, each of which is an equilateral triangle. It is a three-dimensional shape that is commonly used in geometry and mathematics.
