Five-fold symmetry does not exist in nature, including on Earth, due to the constraints of crystallography and the arrangement of atoms in repeating patterns. In three-dimensional space, symmetrical arrangements can only occur in specific ways, such as one-, two-, three-, four-, and six-fold symmetries, which can be accommodated by the crystal lattice structures. Five-fold symmetry creates an incompatible arrangement that cannot tessellate without leaving gaps, making it impossible for natural crystalline structures to form. As a result, while five-fold symmetry can be observed in certain mathematical or theoretical contexts, it does not manifest in natural materials on Earth.

Why five fold symmetry is not possible in crystal?
Five-fold symmetry is not possible in crystals due to the requirement of translational symmetry in three-dimensional space. Crystals are defined by a periodic arrangement of atoms, which necessitates that their symmetry operations lead to a repeating pattern. Five-fold symmetry would create angles that do not allow for a uniform tiling of space, leading to gaps or overlaps, violating the principles of crystallography. Consequently, only symmetries that can be represented by whole-number rotations, such as two-fold, three-fold, four-fold, and six-fold, are permissible in crystalline structures.
Name two living organisms whose shape has five fold symmetry?
star fish ;)
What type of symmetry does a sea lily have?
Sea lilies exhibit pentamerous symmetry, which means they have five-fold symmetry. This type of symmetry is characteristic of many echinoderms, allowing their body structure to be arranged around a central axis in five sections. This arrangement aids in their attachment to substrates and feeding.
A line has two fold symmetry?
Yes, it does.
Does a clover have rotational symmetry and how?
Yes, because if you take a clover and fold it it will fold evenly like paper.

Does a brittle star have asymmetry?
The brittle star has a five-fold symmetry as do all members of class echinadermata.
What are three ways to recognize an echinoderm?
Five fold radial symmetry, vibrant colors, spiny skin

Adult echinodermata have symmetry?
Adult echinoderms have pentaradial symmetry, meaning they are typically organized in a five-fold radial pattern around a central axis. This unique form of symmetry is characteristic of this group of marine animals.
What are the degrees of a Symmetry?
A two-fold symmetry has a 360 degrees rotation. A three-fold rotational symmetry, on the other hand, has 120 degrees, and on a horizontal axis, a symmetry has 180 degrees.
Why 5-fold rotational symmetry is not possible in cube?
A cube has 3-fold rotational symmetry, meaning it can be rotated by 120 degrees and still look the same. It does not have 5-fold rotational symmetry because the cube's faces are not oriented in a way that allows for that type of symmetry. The angles between the faces do not align with the requirements for 5-fold rotational symmetry.
What is four fold symmetry?
It means 4 lines of symmetry as for example a square has 4 lines of symmetry
What type of symmetry does a two fold line have?
It has rotational symmetry of order 2.
A has two-fold rotational symmetry?
line
A line has rotational symmetry?
two-fold
