1. Lines, Line Segments, Rays

2. Line Line- a straight path that goes in two directions without ending. B A AB Read: “Line AB”

3. Ray A ray has one end point and goes on forever in only one direction. D C CD Read: “Ray CD”

4. Line Segment A line segment has two endpoints. F E Read: “Line Segment EF” EF

5. Your Turn! Identify the type of line: line, ray, or line segment. Line Segment

6. Your Turn! Identify the type of line: line, ray, or line segment. Line

7. Your Turn! Identify the type of line: line, ray, or line segment. Ray

8. Your Turn! Identify the type of line: line, ray, or line segment. Line

9. Your Turn! Identify the type of line: line, ray, or line segment. Ray

10. Your Turn! Identify the type of line: line, ray, or line segment. Line Segment

11. Parallel Lines Parallel Lines- lines that never cross or become further apart from each other. K J M L Read: “Line JK is parallel to line LM” ║ LM JK

12. Intersecting Lines Intersecting Lines- lines that cross each other. O R Q P intersects OP QR

13. 90º/Right Angle Perpendicular Lines Perpendicular Lines- lines that cross or meet each other to form square corners (90º angle). U T S Read: “Line ST is perpendicular to line UV” V UV ST ┴

14. Your Turn! Identify if the lines are parallel, perpendicular, or intersecting (not at a perpendicular angle). Parallel
