Parallel lines, Perpendicular lines, and line segments By: Mr. Dunkleberger Mechanicsville Elementary School
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:
ray
. point
line segment
angle
line
right angle
obtuse angle
acute angle
parallel lines
intersecting lines
perpendicular lines
