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
  angles Example
