Study Notes

Points, Lines, and Planes

Coplanar: Points that exist within the same geometric plane, crucial for understanding spatial relationships.
Non-collinear: Refers to points that are not aligned on the same straight line, indicating a multi-dimensional arrangement.
Line: A geometric figure that has no thickness, extending infinitely in two opposite directions; fundamental in geometry.
Ray: A portion of a line with one fixed endpoint, extending infinitely in one direction; useful in angle and light studies.
Point: Represents a specific location in space; has no dimensions, making it vital in defining shapes and figures.
Plane: An infinitely flat surface determined by any three non-collinear points, forming the foundation for two-dimensional geometry.
Opposite Rays: Two rays that share a common endpoint and extend infinitely in opposite directions; important in defining angles and lines.
Non-coplanar: Indicates points that are not situated on the same plane, important for three-dimensional geometry discussions.
Collinear: Points that lie on the same line; essential for understanding linear relationships in geometry.
Line Segment: A section of a line bounded by two endpoints, representing a finite part of a line, relevant in segmentation in geometry.
