Corresponding angles—lie on the same side of a transversal, in
corresponding positions with respect to the two lines that it
intersects (forms the letter F) < 5 and < 6 are corresponding angles
Corresponding Angles Postulate—If two parallel lines are
intersected by a transversal, then corresponding angles are
congruent.
If k ll to l, then <1 is congruent to < 2.
