Equilateral triangles
Equilateral triangles
Triangle (tetrahedron, octahedron, icosahedron) Square (cube) Pentagon (dodecahedron)
They are both 3 dimensional shapes with faces that are polygons.
A polyhedron is closed a 3-dimensional figure whose faces are all polygons. The prefix "octa-" refers to eight and an octahedron is a polyhedron with 8 faces.
The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
a octahedron has 8 faces
Triangles.
A truncated octahedron has 14 faces.
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!
regular pentagons.... Kyah!
