Symmetry in Architecture

A project by Kelli Nipper and Shannon Umberger including:

a) Bilateral Symmetry

b) Rotational and Reflectional Symmetry

c) Cylindrical Symmetry

d) Chiral Symmetry

e) Similarity Symmetry

f) Spiral or Helical Symmetry

g) Translational Symmetry

h) Spherical Symmetry

i) Combinations of Symmetry "Geometry,

according to the Encyclopedia Britannica, is the study of space, and architecture, in the broadest sense of the word, is the creation of space by construction or subdivision. The two disciplines are virtually inseparable with one distinction. Geometry can exist without architecture, but architecture cannot exist without geometry." - William Blackwell, A.I.A.

 

Mandalas

A mandala is a sacred, often circular, design. The word mandala derives from a sanscrit word meaning circle. While mandalas are most often rounded or circular (i.e., more symmetrical) this is not necessary. Beyond the simple attractiveness of these designs, mandalas appearing in different cultures are rich with symbolic and spiritual meanings. This web site is full of graphical symbols with rotational symmetry.
