Honors Geometry 2.6 Notes
If two parallel lines are cut by a
transversal, then corresponding angles are
congruent, alternate interior angles are
congruent, alternate exterior angles are
congruent, and consecutive interior angles
are supplementary.
If two parallel lines are cut by a
transversal, then corresponding angles are
congruent, alternate interior angles are
congruent, alternate exterior angles are
congruent, and consecutive interior angles
are supplementary.
If two lines are cut by a transversal so that:
corresponding angles are congruent, or
alternate interior angles are congruent, or
alternate exterior angles are congruent, or
consecutive interior angles are supplementary,
then the lines are parallel.
Honors Geometry 2.6 Notes
Two lines cut by a transversal are
parallel if and only if the
corresponding angles are
congruent, the alternate interior
angles are congruent, the
alternate exterior angles are
congruent and the consecutive
interior angles are supplementary.
