geometry

Noun
  1. The pure mathematics of points and lines and curves and surfaces (synset 106014015)
    referred to in: math, mathematics, maths - a science (or group of related sciences) dealing with the logic of quantity and shape and arrangement
    associated with:
    • superposition - (geometry) the placement of one object ideally in the position of another one in order to show that the two coincide
    • duality - (geometry) the interchangeability of the roles of points and planes in the theorems of projective geometry
    • plane section, section - (geometry) the area created by a plane cutting through a solid
    • pencil - a figure formed by a set of straight lines or light rays meeting at a point
    • conic, conic section - (geometry) a curve generated by the intersection of a plane and a circular cone
    • eccentricity - (geometry) a ratio describing the shape of a conic section; the ratio of the distance between the foci to the length of the major axis
    • foursquare, square - (geometry) a plane rectangle with four equal sides and four right angles; a four-sided regular polygon
    • angle of inclination, inclination - (geometry) the angle formed by the x-axis and a given line (measured counterclockwise from the positive half of the x-axis)
    • lemniscate - any of several plane algebraic curves in the shape of a figure eight
    • diagonal - (geometry) a straight line connecting any two vertices of a polygon that are not adjacent
    • translate - change the position of (figures or bodies) in space without rotation
    • construct - draw with suitable instruments and under specified conditions
    • inscribe - draw within a figure so as to touch in as many places as possible
    • circumscribe - to draw a geometric figure around another figure so that the two are in contact but do not intersect
    • truncate - replace a corner by a plane
    • congruent - coinciding when superimposed
    • incongruent - not congruent
    • normal - forming a right angle
    • right - having the axis perpendicular to the base
    is a type of: pure mathematics - the branches of mathematics that study and develop the principles of mathematics for their own sake rather than for their immediate usefulness
