Study Notes
Lines and Line Segments
- Line: A continuous collection of points extending infinitely in both directions. Example: Line AB.
- Line Segment: A portion of a line defined by two distinct endpoints.
Types of Lines
- Perpendicular Lines: Lines that intersect to create right angles (90 degrees).
- Parallel Lines: Lines that never meet, remaining constant distance apart.
Intersecting Lines
- Intersecting Lines: Lines that cross at a single point, identifiable by tracing with a finger.
- Intersection: The exact point where two intersecting lines cross.
Real-Life Applications
- Intersecting Roads: Roads that cross each other at a point, creating intersection zones.
- "Real Life" Perpendicular Lines: Situations where two lines form right angles in everyday contexts.
Points and Rays
- Point: An exact location in space without any dimension.
- Ray: A part of a line that has one endpoint and extends infinitely in one direction.
- Endpoint: The specific points that signify the termination of a line segment.
