### Geometry

Geometry (Ancient Greek: ?e?µet??a; geo- 'earth', -metri 'measurement') 'Earth-measuring' is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space. Geometry is one of the oldest mathematical sciences. Initially a body of practical knowledge concerning lengths, areas, and volumes, in the 3rd century BC geometry was put into an axiomatic form by Euclid, whose treatment—Euclidean geometry—set a standard for many centuries to follow. |

History, Modern ; History ; Originated with Robert Dodsley, at the suggestion of Edmund Burke, who was for some years editor and principal contributor. Some time after 1791, the copyright and stock were purchased by Otridge and other booksellers. Messrs. Rivington published a rival continuation, which lasted from 1791 to 1812, and again from 1820 to 1824, when the two were merged into one. Cf. Lowndes. Bibliographer's manual, v. 1.
