Study Notes

Undefined Terms in Geometry

Undefined terms are fundamental figures that cannot be defined using other figures.
Key undefined terms in Geometry: point, line, and plane.

Line

A line serves as a key concept in mathematics, representing a straight path that extends infinitely in both directions.

Collinear

Refers to points or entities that lie on the same straight line.

Segment

A segment is part of a line defined by two endpoints, representing a finite section.

Ray

A ray is a portion of a line that starts at a specific point and extends infinitely in one direction.

Postulate

A postulate is a statement that is accepted as true without proof, often serving as a basis for argument or further reasoning.

Point

In geometry, a point is an exact location in space, represented by coordinates but has no length, width, or height.

Plane

A plane is an infinite two-dimensional flat surface that extends in all directions without boundaries.

Coplanar

Objects are termed coplanar when they lie within the same plane.

Endpoint

An endpoint is a specific location where a line segment or ray concludes.

Opposite Rays

Opposite rays are two rays that share the same endpoint but extend in opposite directions, forming a line.
