noun

, plural ge·om·e·tries.

1. Mathematics. the branch of mathematics that deals with the deduction of the properties, measurement, and relationships of points, lines, angles, and figures in space from their defining conditions by means of certain assumed properties of space.
2. Mathematics. any specific system of the branch of mathematics describing points, lines, angles, and figures in space, that operates in accordance with a specific set of assumptions:

   Euclidean geometry.

3. Mathematics. the study of the branch of mathematics that describes points, lines, angles, and figures in space.
4. Mathematics. a book on the subject of the branch of mathematics that describes points, lines, angles, and figures in space, especially a textbook.
