Title: Parallel lines, Perpendicular lines, and line segments


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
    angles Example
