These are terms commonly used in the study of geometry.
Point, line, plane, Infinitely, distinct points, intersection of lines, parallel lines, concurrent lines, non-concurrent lines, collinear points, non-collinear points, triangular, produced, skew lines

Line
A Line extends Infinitely
(but we cannot draw it like that)

Skew Lines

Collinear Points on a line

triangular

Plane - The image above represents a plane. Planes can be horizontal or vertical and have no thickness. A plane is basically a large flat area.

Concurrent Lines

Parallel lines
