Pro Tip 1/3Geometry Usage
Primarily used in geometry to describe a crystal or a solid shape with eight triangular faces.
A crystal in the shape of an octahedron was used in the experiment.
Pro Tip 2/3Visual Reference
Imagine two pyramids base-to-base to understand an octahedron's structure in 3D.
If you place two pyramids together, you get an octahedron.
Pro Tip 3/3Dice Representation
An octahedron can resemble a standard eight-sided die used in games.
The eight-sided die is basically an octahedron.
