Parallel Lines with a TransversalAngle Relationships Slide2
Parallel Lines are j & kTransversal is lSlide3
Corresponding Angles
“Corresponding” means “matching”, so corresponding angles are the ones at the same location at each intersection.
Which pairs of angles are corresponding? Slide4
Alternate Interior Angles
To “alternate” means to switch back and forth (across the transversal)
“Interior” means “inside” (the parallel lines).
Which pairs of angles are alternate interior? Slide5
Alternate Exterior Angles
To “alternate” means to switch back and forth (across the transversal)
“Exterior” means “outside” (the parallel lines).
Which pairs of angles are alternate exterior? Slide6
Same Side Interior Angles
“Same side” means to be on the same side (of the transversal) (sort of obvious!)
“Interior” means “inside” (the parallel lines).
Which pairs of angles are same side interior? Slide7
PACIFIC AVENUE
ATLANTIC AVENUE
PENNSYLVANIA AVENUE
*
Pacific and Atlantic Ave. are parallel and Pennsylvania acts as a Transversal intersecting the two streets.Slide8
Alternate Interior
Alternate Exterior
When two lines are intersected by a transversal, two pairs of
alternate interior angles
and two pairs of
alternate exterior angles
are formed.
