Points, Lines, Angles, and Planes The Undefined Notions - ShmoopWe'll make these basic units of geometry—the point, the line, and the plane—and call them undefined notions. Since there was nothing that existed before them, we can't use anything to define them—but that doesn't mean we can't explain them.

The Undefined Terms in Geometry (i.e. points, lines & planes)As I understand it, there are three undefined terms (alternatively they are sometimes called primitive notions) in Geometry: Point: A point has 0 dimensions and merely denotes a location. Line: A line has only 1 dimension (that of length, but no others) and spans infinitely in both directions.

Undefined Terms: Point, Line, and Plane (Video & Examples) - Tutors.comNow that you have navigated your way through this lesson, you are able to identify and describe three undefined terms (point, line, and plane) that form the foundation of Euclidean geometry. You can also identify and describe the undefined term, set, used in geometry and set theory.

Undefined Terms - MathBitsNotebook (Geo)In geometry, formal definitions are formed using other defined words or terms. There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the " three undefined terms of geometry ".

Undefined Terms in Geometry - Laying the Foundation of Geometric PrinciplesPoints, lines, and planes are primary examples of undefined terms. Here’s a brief explanation of each: Point: Represents a location in space with no dimensions—no length, width, or height. In a coordinate system, a point is identified by an ordered pair, (x, y). Line: Extends infinitely in both directions but has no thickness.
