Term | Definition |
Coordinate | The number or numbers associated with the location of a point on a line, a plane, or in space |
Coordinatized | a line on which every point is identified with exactly one number and every number is identified with a point on the line |
Distance between two points on a coordinatized line | the length of a segment perpendicular to the planes with an endpoint in each plane |
Plane coordinate geometry | The study of geometric figures using points as ordered pairs of real numbers |
horizontal line | A line with equation y = k on the coordinate plane |
vertical line | A line with an equation x = h on the coordinate plane |
oblique line | a line that is neither horizontal not vertical |
Standard form of an equation of a line | an equation of a line in the form Ax + By = C, where A and B are not both zero |
Slope-intercept form of an equation of a line | A linear equation of the form y = mx + b, where m is the slope and b is the y-intercept |
y-intercept | In the equation of a line, the value of y when x = 0 |
Slope | In the coordinate plane, the change in y-values divided by the corresponding change in x-values |
Discrete point | Points described as dots |
discrete line | lines made up of discrete points |
discrete geometry | The study of discrete points and lines |
graph theory | The geometry of networks |
arc | (A) a path from one point (node) of a network to another point. (B) A set of points made up of two points A and B on a circle (its endpoints) and all points on the circle between A and B/ |
network | a union of points (its vertices, or nodes) and segments (its arcs) connecting them, also called graph |
node (even node, odd node) | an endpoint of an arc in a network. also called vertex |
verticles, vertex | See angle, network, polygon. Plural Vertices |
transversable network | a network in which all the arcs may be traced exactly once without picking up the tracing instrument |
Circularity | the "circling back" that sometimes occurs when one tries to define basic terms; returning to the word that one is trying to define |
underfined terms | a term used without a specific mathematical definition |
figure | a set of points |
space | The set of all points in a geometry |
collinear | points that lie on the same line |
plane figure | a set of points that are all in one plane |
coplanar | points lying in the same plane |
one-dimensional | A space, type of geometry, or figure in which all points are collinear |
two-dimensional | A space, type of geometry, or figure in which all points are coplanar |
three-dimensional | a space, type of geometry, or figure in which all points do not lie in a single plane |
postulate | a statement assumed to be true |
theorem | A statement that follows from postulates, definitions, and other statements already proved. |
Euclidean geometry | The collection of propositions about figures that includes or from which can be deduced those given by the mathematician Euclid around 250 BCE |
parallel lines | Two coplanar lines that have no points in common or are identical |
ray | The set consisting of the distinct points A and B, all points between A and B and all points for which B is between the point A. |
