Parallel lines cut by a transversal form congruent alternate interior angles.
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
Yes. Alternate interior and alternate exterior angles are congruent.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
If a transversal intersects a pair of lines and the alternate angles are congruent, the lines are parallel.
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
The lines are parallel. The only time you will see correpsonding, alternate interior, and alternate exterior angles is with a parallel transversal line.
If two lines are cut by a transversal to form pairs of congruent corresponding angles, congruent alternate interior angles, or congruent alternate exterior angles, then the lines are parallel.
Only if the lines cut by the transversal are parallel.
Yes. Alternate interior and alternate exterior angles are congruent.
Congruent
There's lots of useful things you can discover when parallel lines are cut by a transversal, most of them having to do with angle relationships. Corresponding angles are congruent, alternate interior angles are congruent, same side or consecutive interior angles are supplementary, alternate exterior angles are congruent, and vertical angles are congruent.
It is the transversal line that cuts through parallel lines creating alternate equal angles.
they are congruent i think
a transversal line If a transversal intersects two parallel lines, then the alternate interior angles are congruent.
Then the lines are parallel to each other and the alternate equal angles are created when a transversal line cuts through parallel lines.
Sometimes they are.
Yes. "Alternate interior" angles are always interior. Angles that are not interior as well as alternate are never accurately described as "alternate interior" angles.
