Faces
A triangular based pyramid has 4 faces, 6 edges and 4 vertices
it is the property of solid crystal that they have straight edges and flat faces.
In the angles between faces and the number of edges of equal length

Corundum is in the trigonal crystal system.
A crystal is a polyhedral shape. The number of faces (which means the same thing as sides) depends on the crystal.
Shape: Trigonal

The crystal structure of dolomite is trigonal, meaning that it has threefold symmetry. It consists of layers of carbonate ions alternating with layers of magnesium and calcium ions. This results in a rhombohedral crystal shape.
Crystal faces refer to the natural faces that develop as a crystal grows, showcasing the crystal's geometric shape and symmetry. Cleavage faces, on the other hand, are the flat surfaces along which minerals tend to break when subjected to stress, revealing the internal structure of the mineral.

If a mineral belongs to the hexagonal crystal group, then its crystals have six sides.
Faces
This is a "trigonal pyramid" or "tetrahedron."
Crystal Systems is the word for "observe number and angle of crystal faces."
