Cristal's
The shape of a mineral depends on the chemical structure that the bonds form between atoms in the mineral. A cubic mineral (such as pyrite) has a chemical structure that, as bonds are made, a cubic shape is formed.
Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.
A Circle
From the shape of a mineral crystal, it can be classified into one of the six mineral crystal systems, which is an aid to its identification.

A five sided geometric shape is called a pentagon.
It forms a crystal.
equilateral triangle
Simply a line is formed......
The total distance around a plane geometric shape, i.e. one drawn on a piece of paper, is called the shape's perimeter.
A geometric shape that has 11 sides is called a "hendecagon" or "undecagon." Both terms are acceptable.
