Lines, Line Segments, Rays

Line- a straight path that goes in two directions without ending.

A ray has one end point and goes on forever in only one direction.

E F EF Line Segment Read: “Line Segment EF”
A line segment has two endpoints. E F Read: “Line Segment EF” EF

Read: “Line JK is parallel to line LM”
Parallel Lines Parallel Lines- lines that never cross or become further apart from each other. J K L M Read: “Line JK is parallel to line LM” JK LM

Intersecting Lines- lines that cross each other.
Q P OP intersects QR

Read: “Line ST is perpendicular to line UV”
Perpendicular Lines Perpendicular Lines- lines that cross or meet each other to form square corners (90º angle). U 90º/Right Angle S T Read: “Line ST is perpendicular to line UV” V ST UV
