Basic definitions.
Definition
The foundational terms in geometry including point (a location with no size), line (extends infinitely in both directions), plane (a flat surface extending infinitely), and segment (a part of a line with two endpoints). These are the building blocks for all geometric reasoning.
Examples
Real-world.
- 1 A point is named with a capital letter like point A, a line through two points is written as line AB
- 2 Two points determine exactly one line, and three non-collinear points determine exactly one plane
