Other forms: geometries
Geometry is the mathematics of shapes, lines and angles. Study geometry, a problem in geometry, the geometry of the roof.
Euclidean geometry is the school kind, built on Euclid's axioms; non-Euclidean geometries change one of them and describe curved space, which is what general relativity needs. The geometry of something also means its physical shape and proportions: the geometry of the frame, the geometry of the junction. Note geometric, which in patterns means made of regular shapes, and geometrical, which is the mathematical adjective.

geometry is a field of mathematics.
Greek geometria is ge, earth, plus metron, measure — earth-measuring, because it began as land surveying after the Nile floods erased the field boundaries every year. The most abstract subject in mathematics is named after mud.
