Angle pair relationships

Alt. Interior

These angles are inside the parallel lines

they are congruent

they are one opposite sides of the transversal

they form when a transversal passes through two parallel lines

Consecutive exterior

a pair of angles that are located on the outside of two parallel lines,

they are on the same side of the transversal that intersects them

These angles are supplementary

Two angles in different groups, outside the parallel lines and are on the same side of the transversal

\

\

Corresponding

formed when a transversal intersects two parallel lines

These angles are located on the same side of the transversal in corresponding positions.

angles are in the same spot but different line

they are congruent

Corresponding angles are always formed in pairs and are congruent.

Alt. Exterior

they are congruent

on the opposite sides of the transversal

Angles that are outside of the parallel lines

if two lines are parallel, their alternate exterior angles will be the same degree

Consecutive interior

the pairs of angles that are between two lines and on the same side of the line cutting through the two lines

Angles that are inside the parallel lines

they are one the same side of the transversal

They are supplementary
