Parallel Lines are two lines that are equidistant and never intersect. They have the same slope and they lie on the same plane.

The field has white lines that don’t intersect and are equidistant.

The two buildings between the river are parallel because they are the same distance apart and do not touch.

The lines on the window going only vertical are parallel as well as the two red lines on the floor.

Perpendicular lines are two lines that intersect and form 90 degree angles. They lie in the same plane and have opposite reciprocal slopes.

All the picture in the previous slide have lines that are perpendicular because they intersect and form 90 degree angles.

The vertical and horizontal lines on the rubric cube and door form 90 degree angles.

The red line and silver line on the floor intersect as well as the silver lines on the steel plate.
