The geometric net of an octahedron is a two-dimensional figure that can be folded to form a three-dimensional octahedron. This net of an octahedron consists of eight congruent triangular faces.

In this article, we will learn more about the net of octahedrons. We will explore their diagrams and learn about some of its important characteristics.

## Diagrams of the net of an octahedron

Octahedra are one of the five Platonic solids. These three-dimensional figures have eight congruent triangular faces. That is, the faces have the same shape and the same dimensions.

This means that the geometric net of an octahedron must contain eight congruent triangular faces.

In the following animation, we can see how the net of an octahedron can be folded to form a three-dimensional octahedron.

Since the octahedron consists of two square pyramids joined at their base, we can fold each of these pyramids separately. In the diagram, we see that the lateral faces of each pyramid are folded around the faces that act as temporary bases.

When we talk about octahedrons, we usually mean a regular octahedron, so all eight faces will be congruent equilateral triangles.

## Characteristics of the net of an octahedron

The main characteristic of any geometric net is that they are two-dimensional figures that form three-dimensional figures when folded. In the case of octahedrons, their net consists of eight triangular faces that form a 3D octahedron when folded.

Octahedra have the appearance of two square pyramids connected at their bases. Therefore, we can separate an octahedron into its upper and lower pyramids.

Each pyramid can be folded separately before being connected to form the octahedron. In each pyramid, the central triangle acts as a temporary base.

The temporary base is simply tilted a bit, while the lateral faces are bent until they connect at the main vertex.

In regular octahedrons, all faces are congruent. This means that they have the same shape and the same size.
