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.
