When Parallel Lines Are Cut by a Transversal?

If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. If two parallel lines are cut by a transversal, then the pairs of alternate interior angles

interior angles
The measure of the exterior angle at a vertex is unaffected by which side is extended: the two exterior angles that can be formed at a vertex by extending alternately one side or the other are vertical angles and thus are equal.

are congruent. If two parallel lines are cut by a transversal, then the pairs of alternate exterior angles are congruent.

What happens when parallel lines are cut by a transversal?

If two parallel lines are cut by a transversal, then, Alternate Interior Angles are congruent. If two parallel lines are cut by a transversal, then, Alternate Exterior Angles are congruent. If two parallel lines are cut by a transversal, then corresponding angles are congruent.

When parallel lines are cut by a transversal all acute angles are?

If two parallel lines are cut by a transversal, all the acute angles are congruent to each other and the all the obtuse angles are congruent to each other. If to parallel lines are cut by a transversal, then any of the acute angles will be supplementary to any of the obtuse angles.
