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

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

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

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

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

What is a perpendicular line?
• perpendicular lines
• Two lines that intersect to form four right angles
Example:
