Understanding Basic Geometric Elements
Geometry starts with simple elements that form the foundation of all
shapes!
Lines, line segments, and rays are the basic "ingredients" we use to create all kinds of geometric
figures. They might look similar at first, but each has special properties that make them unique.
Key Differences
1️⃣ Line: Goes on forever in both directions (no endpoints)
2️⃣ Line Segment: Part of a line with two endpoints
3️⃣ Ray: Starts at a point and goes on forever in one direction
Interactive Examples

Real-World Examples
Roads - Can you find examples of lines, segments,
and rays in roads?
Sunlight - Sun rays are perfect examples of rays in
nature!
Rulers - The edge of a ruler represents a
line segment.
Parent Tips 🌟
- Play "I Spy Geometry" - Look for lines, segments, and rays around your home or neighborhood.
- Use straws or string - Create physical examples of each type to help with understanding.
- Connect to art - Many famous artworks use these geometric elements - see if you can spot them!
