1. Parallel lines, Perpendicular lines, and line segments By: Mr. Dunkleberger Mechanicsville Elementary School

2. What is a line? • Line- a straight path in a plane that goes on forever in opposite directions Example: • line AB or line BA

3. What is a point? • point • An exact location in space, usually represented by a dot Example:point A

4. What is a line segment? • line segment • A part of a line that includes two points, called endpoints, and all of the points between them Example: • line segment AB  or line segment BA

5. What is a ray? • ray • A part of a line, with one endpoint, that continues without end in one direction Example:ray CD

6. What is a parallel line? • parallel lines • Lines in a plane that never intersect Example:

7. What is a perpendicular line? • perpendicular lines • Two lines that intersect to form four right anglesExample:
