Crystals have straight and flat edges due to the orderly arrangement of atoms or molecules in a repeating pattern, known as a crystal lattice. As the crystal forms, this structured growth leads to the development of geometric shapes with flat surfaces and sharp edges, reflecting the symmetry of the underlying atomic structure. The specific angles and facets of a crystal are determined by the type of chemical bonds and the crystal system it belongs to. This orderly growth process is what gives crystals their distinct and recognizable shapes.
it is the property of solid crystal that they have straight edges and flat faces.

A flat (2D) shape triangle has 3 straight edges. A triangular pyramid has 6 straight edges. A square pyramid has 8 straight edges. (Note, some vertical edges have already been counted as you move from one face to the next.)

No, a pyramid is a polyhedron with flat faces and straight edges.

Polyhedron is a geometric solid in three dimensions with flat faces and straight edges.
triangula prism
A square pyramid has no curved edges; it consists of eight edges in total, which are all straight. There are four edges forming the base (the square) and four edges connecting the apex to each vertex of the base. Thus, the square pyramid is characterized by its straight edges and flat faces.
No, not all crystals have smooth edges. Some crystals, like pyrite and fluorite, can have natural jagged or rough edges depending on their formation process. Smooth edges are more common in crystals like quartz and amethyst that form in more stable environments.
This shape is a cube.
