geometry
nounUK /d͡ʒiːˈɒm.ɪ.tɹi/ · US /d͡ʒiˈɑ.mə.tɹi/
Etymology From Middle English gemetry, geometrie, from Old French geometrie (modern French géométrie), from Latin geōmetria, from Ancient Greek γεωμετρία (geōmetría, “geometry, land-survey”), from γεωμέτρης (geōmétrēs, “geometer, land measurer”), from γῆ (gê, “earth, land, country”) + -μετρία (-metría, “measurement”), from μέτρον (métron, “a measure”). By surface analysis, geometer + -y or geo- + -metry. Doublet of gematria.
Mathematics, Sciences The branch of mathematics dealing with spatial relationships.
- ANY problem in geometry can easily be reduced to such terms that a knowledge of the lengths of certain straight lines is sufficient for its construction.1925, René Descartes, “The Geometry of Rene Descartes”, in David Eugene Smith, Marcia Latham, transl., [1637, La Géométrie], Cosimo Classics, published 2007, page 2:
Mathematics, Sciences A mathematical system that deals with spatial relationships and that is built on a particular set of axioms; a subbranch of geometry which deals with such a system or systems.
